چکیده
|
Two kinds of carbon-support 20% pd/c catalysts for use in direct ethanol fuel cell (defc) have been prepared by an impregnation reduction method using nabhand nahoas reductants,respectively,in this study. the catalysts were characterized by xrd and tem. the results show that the catalysts had been completely reduced,and the catalysts are spherical and homogeneously dispersed on carbon. the electrocatalytic activity of the catalysts was investigated by electrochemical measurements. the results indicate that the catalysts had an average particle size of 3.3 nm and showed the better catalytic performance,when nabhwas used as the reducing agent. the electrochemical active surface area of pd/c (nabh was 56.4 m2·g-1. the electrochemical activity of the pd/c (nabh was much higher than that of pd/c (naho. © 2013 qiao xia li et al.
