【摘要】 采用低温固相反应法制各了PtSn／C纳米催化剂,研究了该催化剂对甲醇和乙醇氧化的电催化活性。XRD、TEM测试表明,催化剂中金属粒子在碳载体上分布均匀,平均粒径约为4．8nm。Sn的加入导致Pt的晶胞参数增大。电化学测试表明,PtSn/C催化剂对甲醇电氧化表现出更好的催化性能。更多还原

【Abstract】 The PtSn/C catalyst was repared by the low-temperature solid phase reaction method. Its electro-catalytic activity for the methanol oxidation was studied. XRD and TEM analysis indicate that the PtSn/C catalyst is of high dispersion and its mean particle size is about 4.8 nm. The addition of Sn can increase the lattice parameter of Pt. The results of electrochemical measurements demonstrate that PtSn /C catalyst shows better performance for methanol electro-oxidation than ethanol.更多还原
