Abstract

The rising levels of atmospheric CO₂ are a major reason for global warming. CO₂ capture and its conversion into value added chemicals are potential solutions to mitigate this critical issue. This review highlights recent advancements in CO₂ capture methods with approaches for CO₂ reduction to methanol, such as electrocatalysis (EC), photoelectrocatalysis (PEC), and photocatalysis (PC) processes. Special emphasis is placed on catalyst design, system integration, and scalability, as well as the role of interfaces and structural engineering of catalysts in enhancing selectivity, stability, and scalability in EC, PEC, and PC systems. This comprehensive review insights of pathways into future direction and emerging opportunities in CO₂ capture and conversion.
