The conjunction of the PdSn alloy and SnO2 is of interest for improving catalytic activity in formic acid
oxidation (FAO). Here, we report the synthesis of PdSn–SnO2 nanoparticles and a study of their catalytic
FAO activity. Different degrees of interfacial contact between SnO2 and PdSn were obtained using two
different stabilizers (sodium citrate and EDTA) during the reduction process in catalyst preparation.
Compared to the PdSn alloy, PdSn–SnO2 supported on carbon black showed enhanced FAO catalytic
activity due to the presence of SnO2 species. It was also found that interfacial contact between the
PdSn alloy and the SnO2 phase has an impact on the activity towards CO oxidation and FAO.
