1. A preparation method for a hydrothermal carbon composite MOF modified stainless steel mesh cathode, comprising:
(1) evenly mixing deionized water, glucose and acrylic acid, carrying out a hydrothermal reaction at 170-200° C. for 8-24 h, and performing natural cooling, washing and drying;
(2) dissolving terephthalic acid, cobalt nitrate hexahydrate and nickel nitrate hexahydrate in dimethylformamide, then adding acrylic acid modified hydrothermal carbon synthesized in step (1), adding a sodium hydroxide solution dropwise, performing ultrasonic stirring continuously at 100-150° C. for 12-24 h, and washing and drying a resulting product; and
(3) subjecting a hydrothermal carbon composite MOF material prepared in step (2) to high temperature carbonization, preparing an electrode slurry by using the carbonized material, evenly coating the electrode slurry on a treated stainless steel mesh after even stirring, performing drying, and placing a dried electrode in a Muffle furnace for calcination.
