Design of Cu/MoOx for CO2 Reduction via Reverse Water Gas Shift Reaction

CO2 reduction to CO as raw material for conversion chemicals and gasoline fuels via the reverse water–gas shift (RWGS) reaction is generally acknowledged be a promising strategy that makes utilization process more economical efficient. Cu-based catalysts are low-cost have high catalytic performance but insufficient stability due hardening at temperatures. In this work, series of supported by MoOx were synthesized noble metal-free RWGS reactions, effects support on catalyst investigated. The results show introduction can effectively improve reactions. obtained Cu/MoOx (1:1) displays excellent activity with 35.85% 99% selectivity 400 °C. A combination XRD, XPS, HRTEM characterization demonstrate enhances metal-oxide interactions Cu through electronic modification geometric coverage, thus obtaining highly dispersed copper Cu-MoOx interfaces well corresponding oxygen vacancies.
