| 1 | Co-MOF Derived NiCo-LDH Three-Dimensional Nanostructure on Carbon Cloth for High-Performance Supercapacitors显示文摘A well-designed cobalt-based metal organic framework(Co-MOF)derived NiCo layered doubleh ydroxides(NiCo-LDH)three-dimensional porous nanostructures has been fabricated on carbon cloth(CC)b y the ion etching/exchange reaction method. The morphology and structure of the synthesized samples have been characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmissione lectron microscopy(TEM)and X-ray photoelectron spectroscopy(XPS). As an electrode,the optimalN iCo-LDH shows a high specific capacity of 226.3mA·h/g at1A/g. The hybrid supercapacitor(HSC)b ased on NiCo-LDH electrode and activated carbon(AC)achieves a specific energy of 27.39W·h/kg withe xcellent cycling stability(capacity retention of 93.5% after 5000 cycles). | Ping Wang Ning Ding Yirong Wang Yupeng Dang Dandan Han Yen Wei | 2022 | Journal of Harbin Institute of Technology(New Series)2022，29，6： | 1 |
| 2 | Spatially Isolated Noble-Metal-Free Redox Cocatalysts on CdS Nanorods for Increased Photocatalytic Hydrogen Generation显示文摘Spatially isolated oxidation and reduction cocatalysts on a semiconductor can realize efficient charge separation and thereby lead to increased photocatalytic hydrogen generation. However, the effective preparation of such photocatalysts has proven challenging.Herein, we report the facile synthesis of a novel noblemetal-free CdS/MoS/CoPi ternary photocatalyst via a visible light-induced synthesis route, in which MoSreduction cocatalysts were precisely grown on the two terminals of CdS nanorods, while CoPi oxidation cocatalysts were preferentially anchored onto the sidewalls of CdS nanorods. Such spatially isolated MoSand CoPi redox cocatalysts endow CdS nanorods with a rapid charge separation, which enhances their hydrogen generation activity. The CdS/MoS/CoPi photocatalyst with optimized CoPi amount achieves the highest Hgeneration rate of 206 μmol/h, which is 21 and 2 times higher than that achieved by using CdS alone(9.7 μmol/h) and CdS/MoS(105 μmol/h), respectively. The present work highlights the effectiveness of the spatial isolation of reduction and oxidation sites for efficient charge separation and thereby provides a promising strategy for the preparation of highly active photocatalysts. | Xiaomeng Zhang Gege Zhao Zhongfei Li Liang Zhu Yingpeng Cheng Haiwei Du Chuhong Zhu Ya Dang Daochuan Jiang Yupeng Yuan | 2022 | Chinese Journal of Structural Chemistry2022，41，9： | 0 |
