Abstract
The survival and sustainable development of humanity are gravely threatened by climate change, which has recently been elevated to the status of one of the greatest threats to humanity’s survival and security on a worldwide scale. In response to global climate change, how to obtain renewable and clean fuels is an important challenge for the sustainable development of human society. In order to reach the carbon peak and attain carbon neutrality, using CO 2 as a resource has become a crucial aim for human civilization. Converting CO 2 into chemical products with higher added value, that is, CO 2 resource utilization technology can not only achieve CO 2 emission reduction but also have certain economic benefits. The technologies of CO 2 resource utilization primarily include photocatalytic reduction, electrocatalytic reduction, thermal catalytic reduction, and relay catalysis. This paper mainly summarizes the mechanism of CO 2 catalytic conversion technologies and the research status of related catalysts, and summarizes and discusses prospects for the development of the CO 2 catalytic reduction system (catalyst modification, product selectivity improvement, etc.). The ideas and guidance are provided for the development of efficient and stable CO 2 reduction catalysts and the application of CO 2 catalytic reduction technology in the areas of environment and energy.
