Abstract
Cu-based catalysts have been widely recognized as the most representative systems for the hydrogenation of CO2 to methanol, and they also serve as the primary catalysts for the reverse water–gas shift (RWGS) reaction. However, effectively tuning the active sites and reaction pathways of Cu-based catalysts through promoters to overcome the trade-off between CO2 conversion and methanol selectivity remains a significant challenge. In this work, a RWGS + CO-hydrogenation pathway was established on Cu–La/ZrOX (CLZ-X) catalysts by selectively enhancing the interaction between La2O3 and Cu. In situ X-ray absorption spectroscopy (XAS) demonstrated that the coordination environment of Cu was altered upon La2O3…
