Abstract

PdSn/C catalysts with different atomic ratios of Pd to Sn were synthesised by a NaBH~4~ reduction method. Electrochemical tests show that the alloy catalysts exhibit significantly higher catalytic activity and stability for formic acid electrooxidation (FAEO) than the Pd/C catalyst prepared with the same method. XRD and TEM indicate that a particle‐size effect is not the main cause for the high performance. XPS confirms that Pd is modified by Sn through an electronic effect which can decrease the adsorption strength of poisonous intermediates on Pd and thus promote the FAEO greatly.

## Abstract Novel multi‐wall carbon nanotubes (MWCNTs) supported Pd–Au catalyst for electrooxidation of formic acid was prepared and compared with a similarly prepared Pd/MWCNTs and with a commercial Pt–Ru/Vulcan catalyst. The catalysts were prepared by a two‐stage polyol method, followed by H~2~–A
