Abstract

The invention provides a molybdenum disulfide-modified carbon layer-coated cuprous oxide nanowire material grown on the surface of copper foam and its preparation method and application. Sodium hydroxide and ammonium persulfate are dissolved to obtain a mixed solution, and the copper foam is placed in the mixed solution Hydrothermal treatment, the above-mentioned foamed copper obtained by growing copper hydroxide nanowires on the surface is placed in glucose solution for annealing treatment, and the 1T molybdenum disulfide nanosheets are put into the reaction kettle by putting the mixed solution of ammonium molybdate tetrahydrate and thiourea into the reaction kettle In the medium reaction, the annealed copper foam was dip-coated so that 1T molybdenum disulfide nanosheets were evenly distributed on the surface of the carbon layer-coated cuprous oxide nanowires. The one-dimensional molybdenum disulfide-modified carbon layer-coated cuprous oxide nanowires grown in situ on copper foam are uniformly distributed and have a large aspect ratio, which can be directly used as a photoelectrode application without additional binders and conductive agents.

Description

technical field [0001] The invention relates to the fields of new material technology and chemical synthesis technology, and more specifically relates to a molybdenum disulfide-modified carbon layer-coated cuprous oxide nanowire material grown on the surface of foamed copper, and a preparation method and application thereof. Background technique [0002] With the development of modern society, energy problems and environmental problems are becoming more and more serious, so the development and utilization of new energy sources is imminent. Due to the physical properties of the material itself and the easy recombination of photogenerated carriers, there are still huge challenges in the development of technologies that utilize solar energy to produce sustainable and efficient clean energy. The photocathode catalytic material with high-performance catalytic hydrogen evolution reaction and good stability can accelerate the reaction kinetics, thereby improving the photoelectric h...
