What is it about?
Carbon dioxide (CO₂) is best known as a greenhouse gas contributing to climate change. But it can also serve as a raw material for producing valuable chemicals. This review explores how recent advances in catalysis—especially using metal complexes—enable the conversion of CO₂ into fuels, polymers, and fine chemicals. These transformations include making methanol, formic acid, polycarbonates, and acrylic acid derivatives. Because CO₂ is chemically stable and unreactive, these reactions require sophisticated catalytic systems to overcome energy and reaction barriers. The article highlights both fundamental chemistry and industrial efforts to turn CO₂ from a waste product into a useful resource in a future circular carbon economy.

Why is it important?
This work underscores the growing potential of CO₂ as an alternative carbon feedstock for the chemical industry. By integrating catalytic innovation with sustainability goals, the transformations described here could reduce dependency on fossil fuels and cut carbon emissions. The review identifies which reactions are already industrially relevant (e.g., polycarbonate production) and which are still at the research stage (e.g., direct arene carboxylation), offering a roadmap for future development. It emphasizes that long-term progress in CO₂ utilization relies on sustained support for fundamental research and strong collaboration between academia and industry.
Perspectives
Working on this review was both scientifically rewarding and personally meaningful. It reflects decades of collaborative effort, rooted in pioneering work at RWTH Aachen, to reframe carbon dioxide not as waste, but as a resource. Bringing together industrial insights and academic curiosity, we aimed to capture the momentum of a field that stands at the intersection of climate action and chemical innovation. We hope this article will inspire new researchers to push the boundaries of catalysis and accelerate the transition toward more sustainable chemical processes.
