Professor ADV. Energy Mater .: 3D Catalyst Catalyst of Wuhan University of TechnologyHydrogen (H2) is considered to be a promising and * valuable non-renewable fossil fuel substitute, photocatalytic and electrocatalytic decomposition water is considered to be * effective and * environmentally friendly hydrogen production method (HER). Constructing 3D graphene can effectively solve agglomeration problems of graphene sheet layers, but also have the inherent characteristics of the graphene sheet, but also highly low mass density, large specific surface area, interconnect hierarchy and good mechanical stability. Waiting for a series of advantages.
Common imported batteries include: Sanyo battery, Panasonic battery, LG battery, Samsung lithium battery.
In general, the 3D graphene frame has a macro size of approximately a few centimeters and has a nanometer scale, so it is considered to be a bridge that connects nani world and macro world. In view of these unique properties, 3D graphene has broad application prospects in photocatalytic and electrocatalysis. Therefore, in this paper, the Professor of Wuhan University of Science and Technology has reviewed and discussed the preparation of 3D graphel composites and its application in photocatalytic and electrocatalysis. On this basis, the author's three-dimensional graphel composite material Design, preparation and integration presents current challenges and future prospects. This review includes five parts: 3D synthesis method; 2) Main characteristics of 3D graphene; 3) 3D grape alkenyl composites for photocatalytic HER; 4) 3D graphite for electrocatalytic HER Alkenyl composite; 5) Summary and prospect.
