About this collection
As is well known, the massive consumption of fossil fuels, among other human activities, has released substantial amounts of CO2 into the atmosphere, provoking both global warming and dramatic climate changes. As such, carbon dioxide capture and utilisation continues to attract significant attention, and important advances. As an ideal C1 source, efficient transformation of CO2 enables the sustainable synthesis of high value-added chemicals and fuels. Moreover, CO2 can be utilised in a huge number of diverse areas, including as a green tuneable solvent, a working agent, a protective agent, a soft oxidant, and many others.
