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.

Composite material for photocatalytic hydrogen production and photocatalytic hydrogen production catalyst

Ru&#x2014;Ptnanocatalysts with 1&#x2dc;3 atomic layers of Pt-shell were developed for enhancing the catalytic activities. Uniform atomic layers of Pt were successfully deposited on the core nanoparticles with high precision. Using such nanocatalysts as the cathode of the dye-sensitized solar cell (DSSC), the efficiency of DSSC can be significantly increased. For direct methanol fuel cell (DMFC) applications, much higher performance can also be achieved by using such Ru&#x2014;Ptnanocatalysts and the DMFC can be operated at room temperature without the need to raise the cell temperature to above room temperature (such as 80&#xb0; C.).
