中文摘要：
以乙二醇和甲酸钠为还原剂，用间歇式微波加热法快速制备了担载在多壁碳纳米管上的直接甲醇燃料电池阳极催化剂PtSn/MWCNTs.透射电镜（TEM）和X-射线衍射（XRD）测试结果表明，PtSn粒子在MWCNTs上高度分散，平均粒径约为3.2 nm.循环伏安和计时电流实验表明，PtSn/MWCNTs电催化剂较之Pt/MWCNTs有更好的对甲醇氧化催化活性和更强的抗毒化能力.
英文摘要：
PtSn nanoparticles are loaded on multiwalled carbon nanotubes with ethylene glycol and sodium formate using interval microwave heating method. TEM image and XRD patterns reveal that the PtSn/ MWCNTs electrocatalyst exhibite the homogeneous dispersion on MWCNTs, and the mean particles size is about 3. 2 nm. The cyclic voltammetry and chronoamperometry measurements indicate that the PtSn/ MWCNTs present the higher electrocatalytic activity and better tolerance to poisoning species for methanol oxidation than that of Pt/MWCNTs catalyst.
