Abstract:Efficient, clean and non-toxic and non-hazardous catalysts are the focus to realize the decomposition of formic acid (HCOOH) as chemical hydrogen storage material for hydrogen production. In this paper, TiO2 carriers were prepared by hydrothermal method at 453 K, and then NiCl2.6H2O and K2PdCl4 metal solutions with a total amount of 0.1 mmol were added to them by impregnation method to synthesize NiPd/TiO2 catalysts by loading the active components Ni and Pd onto TiO2 carriers, and to investigate their effects on the performance of catalytic formic acid decomposition for hydrogen production. The results of the investigation showed that the reaction conversion frequency (TOF) value of the NiPd/TiO2 catalyst was the largest when the metal Ni:Pd ratio was 2:8 under the catalysis of light, at which the TOF of the catalyst was 3528 h-1, and the activation energy (Ea) of formic acid decomposition on this catalyst was 53.9 kJ/mol.
