With the increase in CO2 emission, the conversion and utilization of CO2 have emerged as a research frontier. Herein, we prepared a series of Pd-Cu bimetallic catalysts by exploiting the activation ability of Pd for hydrogen, which significantly improved the CO2 conversion with H2 at low temperatures. The excellent catalytic performance can be attributed to the interfacial structures formed between Pd-Cu species and oxygen vacancies (VO) on the CeO2 surface, which can determine the activation of CO2, H2 and the formation of intermediate species. Here, we apply for an in situ Pd L3 edge, Ce L3 edge and Cu K edge valence-to-core (Vtc)- RIXS study to follow the dynamics of the Pd-Cu d band with the evolution of the Ce4f-O2p bond structure of CeO2 and identify surface reactant adsorption under RWGS reaction conditions. This study utilizes the uniqueness of the in situ tender RIXS capability at ID26 and will provide a comprehensive understanding of CO2 hydrogenation.
