Key Points

To investigate the mechanism and extent of PdZn alloy formation during the temperature programmed reduction of Pd/ZnO catalysts.
Conducted temperature programmed reduction (TPR) experiments on Pd/ZnO catalysts prepared with various Pd loadings.
Analyzed crystalline phases and surface oxidation states using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS).
Observed selective formation of a distinct PdZn alloy structure driven by hydrogen spillover from Pd to the ZnO support.
Found that the molar amount of reduced ZnO equaled the amount of loaded Pd, confirming complete conversion of Pd into PdZn alloys.
