Abstract
The invention discloses a multi-hole hollow TiO2@C supported PdRu direct methanol fuel cell anode catalyst and a preparation method thereof, and the catalyst is composed of a multi-hole hollow TiO2@C carrier and a PdRu nano-alloy. The multi-hole hollow TiO2@C nano-carrier with high specific surface and the PdRu nano-alloy can form the multi-element catalyst in a recombination manner. With the recombination of C and deposition of the PdAg alloy on the surface of the carrier, the electrical conductivity of TiO2 is improved; the catalytic oxidation of TiO2 on methyl alcohol is greatly improved through the synergistic effect on TiO2 from the recombination of C and the PdRu alloy; meanwhile, intermediate products, such as CO generated by methyl alcohol oxidation, are adsorbed and transferred to the surface of the composite catalyst and are directly deeply oxidized to obtain a final product CO2; in addition, the TiO2@C nano-carrier is stable, and is less prone to oxidation. The price of PdRu is greatly less than that of a precious metal Pt, and the dosage of RuNi in the catalyst is small, thus, the cost of the catalyst is greatly reduced, a CO toxicity resisting capacity of the catalyst is improved, the cost of the catalyst in a direct methanol fuel cell is greatly reduced, and the property of the direct methanol fuel cell is improved.
