The urgent need to address climate change and transition toward sustainable energy systems has positioned CO2 conversion as a pivotal research frontier. This Special Issue focuses on innovative pathways for converting CO2 into value-added chemicals, fuels, and materials through green and energy-efficient approaches. We welcome cutting-edge contributions exploring advanced catalytic strategies, including photocatalytic, photoelectrocatalytic, and electrocatalytic systems, as well as hybrid and emerging technologies. Topics of interest encompass novel catalyst design, mechanistic insights, reaction engineering, scalability challenges, and life-cycle assessments to ensure environmental and economic viability. Interdisciplinary studies bridging chemistry, materials science, and engineering are particularly encouraged. By highlighting breakthroughs in CO2 utilization, this issue aims to accelerate the development of scalable solutions that mitigate carbon emissions while supporting a circular carbon economy. Researchers are invited to submit original research, reviews, and perspectives that advance the science and technology of sustainable CO2 transformation.

Keywords:CO2 conversion, Photocatalysis, Electrocatalysis, Renewable Energy
