| 1 | Two-Dimensional Tellurium:Progress,Challenges,and Prospects显示文摘Since the successful fabrication of two-dimensional(2D)tellurium(Te)in 2017,its fascinating properties including a thickness dependence bandgap,environmental stability,piezoelectric effect,high carrier mobility,and photoresponse among others show great potential for various applications.These include photodetectors,field-effect transistors,piezoelectric devices,modulators,and energy harvesting devices.However,as a new member of the 2D material family,much less known is about 2D Te compared to other 2D materials.Motivated by this lack of knowledge,we review the recent progress of research into 2D Te nanoflakes.Firstly,we introduce the background and motivation of this review.Then,the crystal structures and synthesis methods are presented,followed by an introduction to their physical properties and applications.Finally,the challenges and further development directions are summarized.We believe that milestone investigations of 2D Te nanoflakes will emerge soon,which will bring about great industrial revelations in 2D materials-based nanodevice commercialization. | Zhe Shi Rui Cao Karim Khan Ayesha Khan Tareen Xiaosong Liu Weiyuan Liang Ye Zhang Chunyang Ma Zhinan Guo Xiaoling Luo Han Zhang | 2020 | Nano-Micro Letters2020，12，8： | 8 |
| 2 | Recent Progress,Challenges,and Prospects in Two‑Dimensional Photo‑Catalyst Materials and Environmental Remediation显示文摘The successful photo-catalyst library gives significant information on feature that affects photo-catalytic performance and proposes new materials.Competency is considerably significant to form multi-functional photo-catalysts with flexible characteristics.Since recently,two-dimensional materials(2DMs)gained much attention from researchers,due to their unique thickness-dependent uses,mainly for photo-catalytic,outstanding chemical and physical properties.Photo-catalytic water splitting and hydrogen(H2)evolution by plentiful compounds as electron(e−)donors is estimated to participate in constructing clean method for solar H2-formation.Heterogeneous photocatalysis received much research attention caused by their applications to tackle numerous energy and environmental issues.This broad review explains progress regarding 2DMs,significance in structure,and catalytic results.We will discuss in detail current progresses of approaches for adjusting 2DMs-based photo-catalysts to assess their photo-activity including doping,hetero-structure scheme,and functional formation assembly.Suggested plans,e.g.,doping and sensitization of semiconducting 2DMs,increasing electrical conductance,improving catalytic active sites,strengthening interface coupling in semiconductors(SCs)2DMs,forming nano-structures,building multi-junction nano-composites,increasing photo-stability of SCs,and using combined results of adapted approaches,are summed up.Hence,to further improve 2DMs photo-catalyst properties,hetero-structure design-based 2DMs’photo-catalyst basic mechanism is also reviewed. | Karim Khan Ayesha Khan Tareen Muhammad Aslam Rizwan Ur Rehman Sagar Bin Zhang Weichun Huang Asif Mahmood Nasir Mahmood Kishwar Khan Han Zhang Zhongyi Guo | 2020 | Nano-Micro Letters2020，12，12： | 2 |
| 3 | Emerging monoelemental 2D materials(Xenes)for biosensor applications显示文摘Currently,numerous monoelemental two-dimensional(2D)materials,called Xenes,have been discovered,including graphyne(GD),silicene,germanene,arsenene,borophene.Their structures,fabrication methods,as well as properties have been extensively explored.Based on their single-element composition,high optical response capability,excellent electrical-optical properties,large specific surface area(SSA)and easy modification,Xenes have been widely used in photoelectric applications(detection,modulation,light processing)and biomedicine(biological sensing,drug loading,bioimaging,etc.).Especially in the field of biomedicine,Xenes are expected to induce a great breakthrough.In this review,we introduce the structural characteristics,synthesis and modification methods of several common Xenes respectively.The general properties including optical,electronic,physical and chemical properties of Xenes are summarized.Their diverse utilization as biosensors for nucleic acid sequencing,bioactive detection,cancer diagnosis,etc.are also explicitly explored.Finally,the challenges and future perspectives of Xenes in biosensor are discussed. | Xiaohan Duan Zhihao Liu Zhongjian Xie Ayesha Khan Tareen Karim Khan Bin Zhang Han Zhang | 2023 | Nano Research2023，16，5： | 0 |
