Hydrogen adsorption and reaction on Pd-Cu single atom alloy model catalyst

Abstract

Experiments were conducted to clarify the adsorption of hydrogen on Pd-Cu single atom alloy surface and the effect of hydrogen on adsorbed species.They were conducted at SPring-8 and PF. First, we deposited Pd on a Cu surface. Thereafter, formic acid was adsorbed onto the prepared Pd-Cu surface, and formate was generated. Next, hydrogen was exposed on formate/Pd-Cu. These process were observed by XPS.Analysis of the results and their interpretation will be presented in a lecture.
