【摘要】 采用微波加热还原法制得Pt-Ag复合多壁碳纳米管(MWCNTs)催化剂,然后通过循环伏安法在催化剂上修饰钼酸铵((NH4)6Mo7O244H2O),并研究了钼酸铵修饰后催化剂对氧还原反应的影响。结果表明,修饰后的催化剂明显降低了氧还原的过电势,提高了铂基催化剂的催化效率及氧还原性能。更多还原

【Abstract】 Pt-Ag/MWCNTs electrocatalyst was synthesized by microwave irradiation method and then modified with hexaammonium heptamolybdate tetrahydrate ((NH4)6Mo7O24·4H2O) by using cyclic voltammetry method. The oxygen reduction reaction on the modified catalyst was investigated by linear sweeping voltammetry (LSV). The results indicated that the modification lowered the overpotential, improved the catalytic efficiency for the oxygen reduction reaction.更多还原
