Preparation method of carbon cloth load nickel oxide coated iron oxide nanorod composite material

[0031] First, the purchased carbon cloth was sonicated with 32% concentrated nitric acid, ethanol, and deionized water for 30 minutes respectively.

[0032] 0.65gFeCl 3 (0.05M) and 0.57gNa 2 SO 4 (0.05M) was added to 40ml deionized water, then stirred at room temperature for 30min, the prepared solution was poured into a 50ml polytetrafluoroethylene-lined reactor, and then the treated carbon cloth (such as figure 1 ) into the reaction kettle, keep warm at 120°C for 8h, take it out after cooling, rinse repeatedly with deionized water, dry overnight at 60°C, and obtain iron oxide nanorod precursors with a diameter of 60-70nm and a length of 400-500nm . Weigh 2.38g of Ni(NO 3 ) 2 ·6H 2Add O (0.4M) and 0.3g urea (0.25M) to 20ml deionized water and stir at room temperature for 30min, pour it into a 50ml polytetrafluoroethylene-lined reactor, and then put the precursor into the reactor , kept at 90°C for 9h, rinsed repeatedly with deionized water after cooling, and dried overnig

[0038] 1.3gFeCl 3 (0.1M) and 1.14gNa 2 SO 4 (0.1M) was added to 40ml deionized water, then stirred at room temperature for 30min, poured the prepared solution into a 50ml polytetrafluoroethylene-lined reactor, and then put the treated carbon cloth into the reactor. Insulate at 100°C for 6h, take it out after cooling, rinse repeatedly with deionized water, and dry overnight at 60°C to obtain iron oxide nanorod precursors with a diameter of 70-80nm and a length of 500-600nm. Weigh 1.16g of Ni(NO 3 ) 2 ·6H 2 Add O (0.2M) and 0.6g (0.5M) urea to 20ml deionized water and stir at room temperature for 30min, pour it into a 50ml Teflon-lined reactor, and then put the precursor into the reactor , kept at 80°C for 18h, rinsed repeatedly with deionized water after cooling, and dried overnight at 60°C to obtain a nickel oxide iron oxide h
