An electrolytic water anode plate mesh, its preparation method, and electrolysis device.
ActiveCN118621392BImprove electrocatalytic performanceNo pollution in the processElectrodesNano structuringElectrolysed water
This invention discloses an electrolytic water anode mesh, its preparation method, and an electrolysis apparatus, relating to the field of hydrogen production through water electrolysis. A collision-embedding method is used to deposit electrolytic nickel powder onto the surface of a preheated nickel mesh. By controlling the deposition conditions, a large-area, stable catalytic working layer with a micro / nano structure can be prepared, enhancing the electrolytic catalytic performance of the electrolysis. Compared to plasma spraying for Raney nickel deposition, the method provided by this invention eliminates the need for subsequent alkaline activation, significantly improving preparation efficiency and reducing equipment, maintenance, and manufacturing costs. Furthermore, it avoids the environmental pollution caused by alkaline aluminum removal activators. Compared to plasma spraying for Raney nickel deposition, the micro / nano dual-scale structure working layer prepared by this invention offers controllable micron and nanoscale dimensions and a three-dimensional structure, further enhancing the electrode's electrolytic catalytic performance and demonstrating excellent application prospects.
