中文摘要	in this paper, five pt3sn1/c catalysts have been prepared using three different methods. it was found that phosphorus deposited on the surface of carbon with pt and sn when sodium hypophosphite was used as reducing agent by optimization of synthetic conditions such as ph in the synthetic solution and temperature. the deposition of phosphorus should be effective on the size reduction and markedly reduces ptsn nanoparticle size, and raise electrochemical active surface (eas) area of catalyst and improve the catalytic performance. tem images show ptsnp nanoparticles are highly dispersed on the carbon surface with average diameters of 2 nm. the optimum composition is pt3sn1p2/c (note ptsn/c-3) catalyst in my work. with this composition, it shows very high activity for the electrooxidation of ethanol and exhibit enhanced performance compared with other two pt3sn1/c catalysts that prepared using ethylene glycol reduction method (note ptsn/c-eg) and borohydride reduction method (note ptsn/-b). the maximum power densities of direct ethanol fuel cell (defc) were 61 mw cm(-2) that is 150 and 170% higher than that of the ptsn/c-eg and ptsn/c-b catalyst.
