In this project, the application of bimetallic catalysts of gold and palladium fixed on KIT-6 and TiO2 mesoporous materials in catalytic and photocatalytic decomposition of formic acid with high selectivity for hydrogen preparation was investigated. This effective substrate was used to prepare Au-Pd/KIT-6 catalysts with a difference in gold and palladium, and the prepared catalysts were calcined at 350°C and 550°C. These catalysts were used in the formic acid decomposition to produce hydrogen, and were used to identify the gases produced by the GC.Among the catalysts used, Au-Pd / KIT-6(E) (released gas volume 62mL) showed the best catalytic performance. The effect of various parameters such as solvent volume,amount of catalyst,base solution effect (sodium formate, diethylamine, triethylamine) on formic acid decomposition was investigated using the optimal catalyst.Then titanium dioxide was used as a substrate to prepare Au-Pd/TiO2 catalysts with different percentages of gold using UV light.And the prepared catalysts were calcined at 350 °C. These catalysts were used together with UV light in the decomposition of formic acid to produce hydrogen, and finally the Au-Pd /TiO2 (B) catalyst (52 volume) was selected as the optimal catalyst from among the three catalysts.Finally, the reuse of optimal catalysts during several reactions under optimal conditions was investigated.In order to identify the catalysts, ICP, SEM, XRD, FT-IR, SEM-EDX, TEM and BET techniques were used.
