| 1 | In-situ structure reconstitution of NiCo2Px for enhanced electrochemical water oxidation显示文摘Gaining insight into the structure evolution of transition-metal phosphides during anodic oxidation is significant to understand their oxygen evolution reaction(OER) mechanism, and then design highefficiency transition metal-based catalysts. Herein, NiCo_2P_x nanowires(NWs) vertically grown on Ni foam were adopted as the target to explore the in-situ morphology and chemical component reconstitution during the anodic oxidation. The major factors causing the transformation from NiCo_2P_x into the hierarchical NiCo_2P_x@CoNi(OOH)_x NWs are two competing reactions: the dissolution of NiCo_2P_x NWs and the oxidative re-deposition of dissolved Co^(2+) and Ni^(2+) ions, which is based primarily on the anodic bias applied on NiCo2 Px NWs. The well balance of above competing reactions, and local pH on the surface of NiCo_2P_x NW modulated by the anodic oxidation can serve to control the anodic electrodeposition and rearrangement of metal ions on the surface of NiCo_2P_x NWs, and the immediate conversion into CoNi(OOH)_x. Consequently, the regular hexagonal CoNi(OOH)_x nanosheets grew around NiCo_2P_x NWs.Benefiting from the active catalytic sites on the surface and the sufficient conductivity, the resultant NiCo_2P_x@CoNi(OOH)_x arrays also display good OER activity, in terms of the fast kinetics process, the high energy conversion efficiency, especially the excellent durability. The strategy of in-situ structure reconstitution by electrochemical reaction described here offers a reliable and valid way to construct the highly active systems for various electrocatalytic applications. | Xue Bai Zhiyu Ren Shichao Du Huiyuan Meng Jun Wu Yuzhu Xue Xiaojun Zhao Honggang Fu | 2017 | Science Bulletin2017，62，22： | 8 |

| 3 | Two-in-one solution using insect wings to produce graphene-graphite films for efficient electrocatalysis显示文摘Natural organisms contain rich elements and naturally optimized smart structures,both of which have inspired various innovative concepts and desig ns in human society.In particular,several natural organisms have been used as element sources to synthesize low-cost and environmentally friendly electrocatalysts for the oxygen reduction reaction(ORR)in fuel cells and metal-air batteries,which are clean energy devices.However,to date,no naturally optimized smart structures have been employed in the synthesis of ORR catalysts,including graphene-based materials.Here,we demonstrate a novel strategy to synthesize graphene-graphite films(GGFs)by heating butterfly wings coated with FeCI3 in N2,in which the full power of natural organisms is utilized.The wings work not only as an element source for GGF generation but also as a porous supporting structure for effective nitrogen doping,two-dimensional spreading,and double-face exposure of the GGFs.These GGFs exhibit a half-wave potential of 0.942 V and a H2O2 yield of<0.07%for ORR electrocatalysis;these values are comparable to those for the best commercial Pt/C and all previously reported ORR catalysts in alkaline media.This two-in-one strategy is also successful with cicada and dragonfly wings,indicating that it is a universal,green,and cost-effective method for developing high-performance graphene-based materials. | Huaiyu Li Lihan Zhang Long Li Chaowen Wu Yajiao Huo Ying Chen Xijun Liu Xiaoxing Ke Jun Luo Gustaaf Van Tendeloo | 2019 | Nano Research2019，12，1： | 3 |
| 4 | Emerging porous nanosheets:From fundamental synthesis to promising applications显示文摘Metal-organic framework(MOF)nanosheets and covalent organic framework(COF)nanosheets as emerging porous materials nanosheets have captured increasing attention owing to their attractive properties originating from the advantages of large lateral size,ultrathin thickness,tailorable physiochemical environment,flexibility and highly accessible active sites on surface,and the applications of them have been explored in a wide range of fields.Although MOF and COF nanosheets own many similar properties,their applications in various fields show significant differences,probably due to their different compositions and bonding modes.Hence,we summarize the recent progress of MOF and COF nanosheets by comparative analysis on their advantages and limitations in synthesis and applications,providing a more profound and full-scale perspective for researchers or beginners to understand this field.Herein,the categories of preparation methods of MOF and COF nanosheets are firstly discussed,including top-down and bottom-up methods.Secondly,the applications of MOF and COF nanosheets for separation,catalysis,sensing and energy storage are summarized.Finally,based on current achievements,we put forward our personal insights into the challenges and outlooks on the synthesis,characterizations,and promising applications for future research of MOF and COF nanosheets. | Yun Fan Jia Zhang Yu Shen Bing Zheng Weina Zhang Fengwei Huo | 2021 | Nano Research2021，14，1： | 3 |
