| 中文摘要 | the ptau/c alloy catalyst is firstly synthesized by the co-reduction of both metal precursors under microwave conditions and then heat-treated to enable the migration of au atoms to the exterior surface of the obtained ptau/c catalyst. the bulk crystallite structures and the surface au contents of ptau/c catalysts are characterized by x-ray diffraction and x-ray photoelectron spectroscopy, respectively. the electrocatalytic activity and durability measurements exhibit the superior catalytic performance of ptau/c catalysts over that of pt/c catalyst on formic acid electrooxidation. moreover, the initial and final activity after 3600 s reaction of the heat-treated ptau/c alloy catalyst is two and five times as high as that of the untreated ptau/c catalyst. the performance enhancement of the ptau/c catalysts is discussed in terms of the electronic effect and ensemble effect.
