WebNanostructured multicomponent hydroxide has recently drawn wide attention as positive material for high-performance supercapacitors. Herein, a multi-dimensional Co(OH)F@NiCo-LDH (LDH = layered double hydroxide) composite with layered nanocages has uniformly grown on nickel foam (NF) by a solvent-assisted process, which involves … Web此外,Co-F上H*生成的吉布斯自由能(ΔG H*)比纯Co上更负。这说明Co-F阴极有利于H 2 O解离生成H*,有利于1a的加氢。以Co(OH)F纳米线(NW)为前驱体,采用电还原法制备了表面F修饰Co催化剂,标记为Co-F。在Co …
