Bi-doped cuprous sulfide mesoporous nanobelt array structure material, preparation method and application of Bi-doped cuprous sulfide mesoporous nanobelt array structure material

*The invention provides a Bi-doped cuprous sulfide mesoporous nanobelt array structure material and a preparation method and application thereof.The preparation method comprises the steps that foamy copper is obliquely placed in a mixed solution containing a copper source, a sulfur source, an alkali source, a morphology regulating agent and a bismuth source, a hydrothermal reaction is conducted, and a three-dimensional net-shaped nanostructure material composed of Bi < 3 + >-doped Cu2S mesoporous nanobelts is prepared. The mesoporous nanobelt structure provides abundant active sites for adsorption of CO2 molecules and intermediates, Bi < 3 + > is doped into Cu2S crystal lattices, the electrochemical active area of the catalyst is increased, the conductivity of the catalyst is improved, and the transfer rate of interface charges is increased. Bi < 3 + > doping adjusts the electronic structure of Cu2S, promotes CO2 adsorption, enhances the combination of * CO2 , enhances the adsorption of a wired * COL inte
