Composite material for photocatalytic hydrogen production and photocatalytic hydrogen production catalyst

Abstract

A composite material for photocatalytic hydrogen production and a photocatalytic hydrogen production catalyst are provided. The composite material includes a plurality of inorganic semiconductor particles and a linear conjugated polymer material. The conductive band of a material of the inorganic semiconductor particles is higher than the reduction potential of hydrogen, and the linear conjugated polymer material is compounded on a surface of each of the inorganic semiconductor particles, wherein the difference in the energy level of the lowest unoccupied molecular orbital (LUMO) of the linear conjugated polymer material and the conductive band of the material of the inorganic semiconductor particles is within 2 eV.
