摘要
Hierarchical hollow tungsten trioxide spheres (HHTTS) prepared using sacrificial template methods have been used as the support of Pd nanoparticles. The resultant Pd/HHTTS catalyst exhibits low onset potential, a large electrochemical surface area, excellent catalytic activity and stability compared with Pd/C due to the synergistic effect between Pd and HHTTS capable of promoting oxidation of HCOOH directly to CO2 and the hydrogen spillover effect which greatly accelerates the dehydrogenation of HCOOH oh Pd.
