Synthesis of carbon-supported PdSn-SnO sub(2) nanoparticles with different degrees of interfacial contact and enhanced catalytic activities for formic acid oxidation

The conjunction of the PdSn alloy and SnO sub(2) is of interest for improving catalytic activity in formic acid oxidation (FAO). Here, we report the synthesis of PdSn-SnO sub(2) nanoparticles and a study of their catalytic FAO activity. Different degrees of interfacial contact between SnO sub(2) and...

Description
Summary:The conjunction of the PdSn alloy and SnO sub(2) is of interest for improving catalytic activity in formic acid oxidation (FAO). Here, we report the synthesis of PdSn-SnO sub(2) nanoparticles and a study of their catalytic FAO activity. Different degrees of interfacial contact between SnO sub(2) 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-SnO sub(2) supported on carbon black showed enhanced FAO catalytic activity due to the presence of SnO sub(2) species. It was also found that interfacial contact between the PdSn alloy and the SnO sub(2) phase has an impact on the activity towards CO oxidation and FAO.
