| 1 | Progress on Porous Ceramic Membrane Reactors for Heterogeneous Catalysis over Ultrafine and Nano-sized Catalysts显示文摘Heterogeneous catalysts with ultrafine or nano particle size have currently attracted considerable attentions in the chemical and petrochemical production processes, but their large-scale applications remain challenging because of difficulties associated with their efficient separation from the reaction slurry. A porous ceramic membrane reactor has emerged as a promising method to solve the problem concerning catalysts separation in situ from the reaction mixture and make the production process continuous in heterogeneous catalysis. This article presents a review of the present progress on porous ceramic membrane reactors for heterogeneous catalysis, which covers classification of configurations of porous ceramic membrane reactor, major considerations and some important industrial applications. A special emphasis is paid to major considerations in term of application-oriented ceramic membrane design, optimization of ceramic membrane reactor performance and membrane fouling mechanism. Finally, brief concluding remarks on porous ceramic membrane reactors are given and possible future research interests are also outlined. | JIANG Hong MENG Lie CHEN Rizhi JIN Wanqin XING Weihong XU Nanping | 2013 | Chinese Journal of Chemical Engineering2013，21，2： | 9 |
| 2 | Manipulation of confined structure in alcohol-permselective pervaporation membranes显示文摘Alcohol-permselectivity pervaporation has been arousing increasingly more attention in bioalcohol production due to the advantages of environmental friendliness, low energy consumption and easy coupling with fermentation process. With the intrinsic feature of larger molecules preferentially permeating and the consequent inferiority in selective diffusion, the development of alcohol-permselective membrane is relatively retarded compared with water-permselective membrane. This review presents the prevalent membrane materials utilized for alcohol-permselective pervaporation and emphatically expatiates the representative and important developments in the past five years from the aspect of tuning confined structure in membranes. In particular, the diverse structure tuning methods are described with the classifications of physical structure and chemical structure. The corresponding structure-performance relationships in alcohol-permselective pervaporation membranes are also analyzed to identify the objective of structure optimization. Furthermore, the tentative perspective on the possible future directions of alcohol-permselective pervaporation membrane is briefly presented. | Jing Zhao Wanqin Jin | 2017 | Chinese Journal of Chemical Engineering2017，25，11： | 8 |
| 3 | Two-Dimensional-Material Membranes:Manipulating the Transport Pathway for Molecular Separation显示文摘CONSPECTUS:The discovery of graphene triggers a new era of two-dimensional(2D)materials,which exhibit great potential in condensed matter physics,chemistry,and materials science.Meanwhile,the booming of 2D materials brings new opportunities for the next generation of high-performance(high permeability,selectivity,and stability)separation membranes.Two-dimensional materials with atomic thinness can serve as new building blocks for fabricating ultrathin membranes possessing the ultimate permeation rate.The plane structure with micrometer lateral dimensions provides an excellent platform for the orderly alignment of the nanosheets.Moreover,the apertures of two-dimensional-material membranes(2DMMs),including the in-plane nanopores and interlayer channels,can contribute to the fast and selective transport of small molecules/ions related to molecular separation.Therefore,the emerging 2D materials with various nanostructures,including graphene oxide(GO),zeolite nanosheets,metal−organic framework(MOF)nanosheets,and transition-metal carbides/carbonitrides(MXene),can be assembled into highperformance membranes.Various assembly methods such as filtration,spin coating,and hot dropping have been employed to fabricate 2DMMs,while the processes for separating small molecules/ions tend to demand higher precision,especially in water desalination and gas separation.The nanostructures of 2DMMs and the physicochemical properties of transport pathway need to be finely tuned to meet the requirement.In addition,the stability of 2DMMs,which is critical to the large-scale implementation,must be taken into consideration as well.In this Account,we discuss our recent progress in manipulating molecular transport pathways in 2DMMs by optimizing the assembly behavior of 2D nanosheets,tuning the microstructure of interlayer channels,and controlling the physicochemical properties of the membrane surface.Assembly methods,including vacuum suction assembly,polymer-induced assembly,and external force-driven assembly,have been proposed to construct ordered laminates for molecular transport.The size and chemical structure of interlayer channels were further tailored by strategies such as nanoparticle intercalation,cationic control,and chemical modification.Interestingly,the manipulation of surface properties of 2DMMs was proven to contribute to fast molecular transport through interlayer channels.Moreover,the issues concerning 2DMMs toward practical applications are discussed with an emphasis on the substrate effect,molecular bridge strategy,and preliminary progress in large-scale fabrication.Finally,we conclude this Account with an overview of the remaining challenges and the new opportunities that will be opened up for 2DMMs in molecular separation. | Long Cheng Gongping Liu Jing Zhao Wanqin Jin | 2021 | Accounts of Materials Research2021，2，2： | 4 |
| 4 | Design and Fabrication of Ceramic Catalytic Membrane Reactors for Green Chemical Engineering Applications显示文摘Catalytic membrane reactors(CMRs),which synergistically carry out separations and reactions,are expected to become a green and sustainable technology in chemical engineering.The use of ceramic membranes in CMRs is being widely considered because it permits reactions and separations to be carried out under harsh conditions in terms of both temperature and the chemical environment.This article presents the two most important types of CMRs:those based on dense mixed-conducting membranes for gas separation,and those based on porous ceramic membranes for heterogeneous catalytic processes.New developments in and innovative uses of both types of CMRs over the last decade are presented,along with an overview of our recent work in this field.Membrane reactor design,fabrication,and applications related to energy and environmental areas are highlighted.First,the configuration of membranes and membrane reactors are introduced for each of type of membrane reactor.Next,taking typical catalytic reactions as model systems,the design and optimization of CMRs are illustrated.Finally,challenges and difficulties in the process of industrializing the two types of CMRs are addressed,and a view of the future is outlined. | Guangru Zhang Wanqin Jin Nanping Xu | 2018 | Engineering2018，4，6： | 4 |
| 5 | Two-dimensional MXene hollow fiber membrane for divalent ions exclusion from water显示文摘Two-dimensional material membranes with fast transport channels and versatile chemical functionality are promising for molecular separation.Herein,for the first time,we reported design and engineering of two-dimensional Ti_(3)C_(2)Tx MXene(called transition metal carbides and nitrides)membranes supported on asymmetric polymeric hollow fiber substrate for water desalination.The membrane morphology,physicochemical properties and ions exclusion performance were systematically investigated.The results demonstrated that surface hydrophilicity and electrostatic repulsion and size sieving effect of interlayer channels synergistically endowed the MXene hollow fiber membrane with fast water permeation and efficient rejection of divalent ions during nanofiltration process. | Guozhen Liu Yanan Guo Baochun Meng Zhenggang Wang Gongping Liu Wanqin Jin | 2022 | Chinese Journal of Chemical Engineering2022，35，1： | 3 |
| 6 | Natural gas purification by asymmetric membranes: An overview显示文摘Natural gas, as a very important source of energy and chemical feedstock, can be used in place of coal to lower net carbon dioxide emissions.Membrane separation technology is an attractive alternative for natural gas purification where the impurities represented by acid gases(CO_(2) and H_(2)S) as well as inert gases(N_(2)) must be removed to meet the transportation and usage specifications. From the economic benefits viewpoint,asymmetric membranes are required for industrial manufacture and applications. This paper aims to review the latest development of various kinds of asymmetric membranes for natural gas purification, mainly focusing on CO_(2) removal from CH_(4), including H_(2)S and N_(2) separation from CH_(4) as well. According to material types, polymeric, inorganic, mixed-matrix and carbon molecular sieve membranes are introduced. The associated fabrication approaches and transport properties are discussed for each kinds of asymmetric membranes. Towards the practical implementation, an emphasis is placed on hollow fiber asymmetric structure for these polymeric, mixed-matrix and carbon molecular sieve membranes. | Xi Chen Gongping Liu Wanqin Jin | 2021 | Green Energy & Environment2021，6，2： | 3 |
| 7 | Polydimethylsiloxane (PDMS) Composite Membrane Fabricated on the Inner Surface of a Ceramic Hollow Fiber: From Single-Channel to Multi-Channel显示文摘The fabrication of a separation layer on the inner surface of a hollow fiber (HF) substrate to form an HF composite membrane offers exciting opportunities for industrial applications, although challenges remain. This work reports on the fabrication of a polydimethylsiloxane (PDMS) composite membrane on the inner surface of a single-channel or multi-channel ceramic HF via a proposed coating/crossflow approach. The nanostructures and transport properties of the PDMS HF composite membranes were optimized by controlling the polymer concentration and coating time. The morphology, surface chemistry, interfacial adhesion, and separation performance of the membranes were characterized by fieldemission scanning electron microscope (FE-SEM), attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy, the nano-indentation/scratch technique, and pervaporation (PV) recovery of bio-butanol, respectively. The formation mechanism for the deposition of the PDMS layer onto the inner surface of the ceramic HF was studied in detail. The optimized inner surface of the PDMS/ceramic HF composite membranes with a thin and defect-free separation layer exhibited a high flux of ~1800 gm-2h-1 and an excellent separation factor of 35–38 for 1 wt% n-butanol/water mixtures at 60 C. The facile coating/cross-flow methodology proposed here shows great potential for fabricating inner-surface polymer-coated HFs that have broad applications including membranes, adsorbents, composite materials, and more. | Ziye Dong Haipeng Zhu Yingting Hang Gongping Liu Wanqin Jin | 2020 | Engineering2020，6，1： | 2 |
