The state-of-the-art industry based on carbon-intensive energy causes major concerns on energy and environmental sustainability.Carbon neutrality is now a worldwide consensus and an impera-tive task.Efficient capture and/or conversion of carbon dioxide(CO2) is key-enabling to achieve carbon neutrality.Challenges of the aforenamed task lie in the chemical inertness of CO2 and costly separation of CO2 from flue gases.Capture and conversion of CO2 on the occasions of generation,namely in-situ CO2 conversion,are highly desired.
