Catalytic formic acid decomposition to hydrogen is an important route for hydrogen storage and hydrogen energy utilization. Dendritic ionic polymer microspheres were prepared by quaternization and polymerization using 4-vinylpyridine and 1, 3, 5-tris(bromomethyl)-2, 4, 6-trimethylbenzene as the precursors. After loading Pd nanoparticles, they were used to catalyze decomposition of formic acid to hydrogen. Pd nanoparticles with high dispersion, small size, uniform particle size distribution and optimized electronic structure were obtained, which is benefited from the ion-exchange and N-rich characteristic of the microspheres. The effects of formic acid concentration and reaction temperature on the hydrogen production rate were investigated. The results indicated that formic acid can be completely decomposed within 30 min under the optimal reaction conditions (50 ℃, 1 mol/L of formic acid, the molar ratios of formic acid to palladium and sodium formate are 200 and 3, respectively). There is no significant decrease in the activity after the catalyst is used for 4 times.
