[0002] As the global climate change problem becomes increasingly serious, reducing greenhouse gas emissions has become a major challenge facing the world. Carbon dioxide (CO2) is one of the main components of greenhouse gases, and its excessive emissions directly lead to global warming, an increase in extreme weather events and an imbalance in the ecosystem. Therefore, the development of technologies that can effectively reduce CO2 emissions or convert CO2 into useful resources has important environmental and economic significance. CO2 capture and conversion technology (CCU) is one of the important ways to solve this problem. CCU technology is committed to capturing carbon dioxide and converting it into valuable chemicals or fuels, which can not only reduce CO2 emissions, but also achieve resource utilization.
