英文摘要	It is generally accepted that carbon dioxide (CO2) is one of the most important greenhouse gases and a primary factor in the acceleration of climate change. Methanation, which involves converting CO2 to methane in the presence of renewable hydrogen, is a plausible technique for achieving net-zero atmospheric CO2 concentrations. Nevertheless, the development of effective catalytic systems continues to be a significant barrier tor CO2 methanation. CeO2-based catalysts for CO2 methanation could benefit from tuning their oxygen vacancies (OVs) to increase catalytic performance. This review examines and discusses in depth a number of different characterization methodologies for measuring OVs. Additionally, this review focuses specifically on the role that OVs play in various CeO2- based catalysts as well as the numerous tuning strategies that may be used to increase the number of OVs in these catalysts. This study could give scientists new ideas for how to improve catalytic CO2 methanation.& COPY; 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
