This book presents the current status of CO₂ utilization from fundamental studies to industrial tests. With the development of renewable energy, carbon dioxide will become an important feedstock for the synthesis of fuels and chemicals, and CO₂ utilization must be the final solution for the carbon dioxide issues. This book discusses the effective techniques for activating inert carbon dioxide and various approaches for CO₂ conversion, such as homogeneous catalytic conversion, homogeneous catalytic conversion, heterogeneous...
