| 1 | Microenvironment regulation of M-N-C single-atom catalysts towards oxygen reduction reaction显示文摘The development of cost-effective,robust,and durable electrocatalysts to replace the expensive Pt-based catalysts towards oxygen reduction reaction(ORR)is the trending frontier research topic in renewable energy and electrocatalysis.Particular attention has been paid to metal-nitrogen-carbon(M-N-C)single atom catalysts(SACs)due to their maximized atom utilization efficiency,biomimetic active site,and distinct electronic structure.More importantly,their catalytic properties can be further tailored by rationally regulating the microenvironment of active sites(i.e.,M-N coordination number,heteroatom doping and substitution.Herein,we present a comprehensive summary of the recent advancement in the microenvironment regulation of MN-C SACs towards improved ORR performance.The coordination environment manipulation regarding central metal and coordinated atoms is first discussed,focusing on the structure-function relationship.Apart from the near-range coordination,longrange substrate modulation including heteroatom doping,defect engineering is discussed as well.Besides,the synergy mechanism of nanoparticles and single atom sites to tune the electron cloud density at the active sites is summarized.Finally,we provide the challenges and outlook of the development of M-N-C SACs. | Li Zhang Qinglei Meng Ruixue Zheng Liuqing Wang Wei Xing Weiwei Cai Meiling Xiao | 2023 | Nano Research2023，16，4： | 2 |

| 3 | Tumor-responsive dynamic nanoassemblies for boosted photoimmunotherapy显示文摘Photoimmunotherapy(PIT)is an emerging therapeutic approach that integrates phototherapy and immunotherapy to eliminate primary tumors under an appropriate dosage of local light irradiation,while simultaneously preventing tumor metastasis and recurrence by activating the host antitumor immune response.Tumor-responsive dynamic nanoassemblies(TDNs)have evolved from being a mere curiosity to a promising platform for high-performance PIT.However,the dynamic nano-bio interaction between TDNs and tumor microenvironment remains poorly understood,which shall be critical for precise control of TDNs assembling/disassembling behavior and superior PIT efficacy.To deepen the understanding of the structure–function relationship of TDNs,this review introduces the rational design,nano-bio interactions,and controllable functionalities of cutting-edge TDNs for enhanced PIT.Moreover,the synergetic mechanism between TDNs-based PIT and immunomodulatory agents-mediated immunomodulation is particularly emphasized.Finally,the challenges and future perspectives in this emerging field are assessed. | Dao Shi Nan Wang Jie Zhang Xi Hu Qiyue Wang Ruixue Xiao Baoyue Ding Fangyuan Li Daishun Ling | 2023 | Nano Research2023，16，8： | 1 |

| 7 | Highly ordered Janus CdS-Au-TiO_(2) Z-scheme structure with high efficiency in photocatalysis显示文摘Precise structural control had attracted tremendous interest in nanosynthesis due to its great importance in tailoring the physical properties of nanomaterials.Here we report the synthesis of highly ordered Cd S-Au-TiO_(2) ternary Janus structure via templateprotected sequential growth and conversion method.Arising from the integration of the rectification effect of Au-CdS and AuTiO_(2) Schottky barriers,the Janus configuration of the Cd S-TiO_(2) domains,the plasmonic effect of Au nanosphere,and the Zscheme charge transportation,the Cd S-Au-TiO_(2) Janus structure showed high efficiency in the model photocatalytic degradation of methyl orange(MO)dye.Importantly,the well-defined structural order allowed the identification of the correlation between the structure and the catalytic performance.We believe that the synthetic control and the mechanism insights would help the design and synthesis of sophisticated nanostructures,and would eventually promote their applications in photocatalysis fields. | Ruixue Xiao Jie Zhang Tingting Jiang Yefan Zhou Yun Wang Wenjia Xu Yuhua Feng | 2023 | Science China Chemistry2023，66，6： | 0 |
| 8 | Accelerating myelin degeneration in Alzheimer's disease mice显示文摘Alzheimer's disease(AD)is the most common cause of dementia,mainly manifested by cognition decline and memory loss.Recent research has revealed that myelin plays an important role for memory capacity.However,the myelin dynamics in AD brains remains unclear.In this study,we examined the myelin changes in the APP/PS1 mutant brains by immunostaining and transmission EM,and used the PLP-CreERt;mTomato/mGFP(mT/mG);APP/PS1 line to label and track pre existing myelin at the age of 4 months.Our results indicated that MBP expression was reduced in the 13-month old APP/PS1AD brains as compared to the age matched wild type brains. | Chen Jingfei Liu Kun Wang Fei Li Ruixue Xiao Lan Mei Feng | 2021 | 解剖学杂志2021，44，S01： | 0 |
| 9 | Atomically dispersed Fe sites on hierarchically porous carbon nanoplates for oxygen reduction reaction显示文摘Developing cost-effective,robust and stable non-precious metal catalysts for oxygen reduction reaction(ORR) is of paramount importance for electrochemical energy conversion devices such as fuel cells and metal-air batteries.Although Fe-N-C single atom catalysts(SACs) have been hailed as the most promising candidate due to the optimal binding strength of ORR intermediates on the Fe-N_(4) sites,they suffer from serious mass transport limitations as microporous templates/substrates,i.e.,zeolitic imidazolate frameworks(ZIFs),are usually employed to host the active sites.Motivated by this challenge,we herein develop a hydrogen-bonded organic framework(HOF)-assisted pyrolysis strategy to construct hierarchical micro/mesoporous carbon nanoplates for the deposition of atomically dispersed Fe-N_(4) sites.Such a design is accomplished by employing HOF nanoplates assembled from 2-aminoterephthalic acid(NH_(2)-BDC) and p-phenylenediamine(PDA) as both soft templates and C,N precursors.Benefitting from the structural merits inherited from HOF templates,the optimized catalyst(denoted as Fe-N-C SAC-950) displays outstanding ORR activity with a high half-wave potential of 0.895 V(vs.reversible hydrogen electrode(RHE)) and a small overpotential of 356 mV at 10 mA cm^(-2) for the oxygen evolution reaction(OER).More excitingly,its application potential is further verified by delivering superb rechargeability and cycling stability with a nearly unfading charge-discharge gap of 0.72 V after 160 h.Molecular dynamics(MD) simulations reveal that micro/mesoporous structure is conducive to the rapid mass transfer of O_(2),thus enhancing the ORR performance.In situ Raman results further indicate that the conversion of O_(2) to~*O_(2)-the rate-determining step(RDS) for Fe-N-C SAC-950.This work will provide a versatile strategy to construct single atom catalysts with desirable catalytic properties. | Ruixue Zheng Qinglei Meng Hao Zhang Teng Li Di Yang Li Zhang Xiaolong Jia Changpeng Liu Jianbing Zhu Xiaozheng Duan Meiling Xiao Wei Xing | 2024 | Journal of Energy Chemistry2024，90，3： | 0 |
| 10 | Recent Advances in Stability Improvement Strategies of M-N_(x)/C Catalysts Towards Oxygen Reduction Reaction显示文摘Although fuel cells possess advantages of high energy conversion efficiency and zero-carbon emission,their large-scale commercialization is restricted by expensive and scarce platinum(Pt)catalysts.Metal-nitrogen-carbon(M-Nx/C)catalysts are hailed as the most promising candidates to replace Pt due to their considerable oxygen reduction reaction(ORR)activity and low cost.Despite tremendous progress in terms of active site identification and activity improvement being achieved in the past few decades,the M-Nx/C catalysts still suffer from insufficient durability,which drastically limits their practical application.In this regard,understanding degradation mechanisms and customizing stabilization strategies are of significant importance yet challengeable.In this review,we summarize the recent advances in the stability improvement of M-Nx/C catalysts.The stability test protocols of the M-Nx/C are firstly introduced.Subsequently,with the combination of advanced ex situ and in situ characterization techniques and density functional theory calculation,we present a comprehensive overview of the main degradation mechanisms during ORR process.Aiming at these deactivation issues,a variety of novel improvement strategies are developed to enhance the stability of M-Nx/C.Finally,the current challenges and prospects to design highly stable M-Nx/C catalysts are also proposed. | Xiaolong Jia Qinglei Meng Ruixue Zheng Xiaohui Liu Yaling Zhao Changpeng Liu Meiling Xiao Wei Xing | 2023 | Renewables2023，1，6： | 0 |
