Abstract

Utilizing sunlight as a renewable energy source, photocatalysis offers a potential solution to global warming and energy shortages by converting CO₂ into useful solar fuels, including CO, CH₄, CH₃OH, and C₂H₅OH. Among the various formulations investigated, copper-based photocatalysts stand out as particularly appealing for CO₂ conversion due to their cost-effectiveness and higher abundance in comparison to catalysts based on precious metals. This literature review provides a thorough summary of the latest developments in copper-based photocatalysts used for CO₂ reduction reactions, including metallic copper, copper oxide, and cuprous oxide photocatalysts. The review also provides a categorical summary of the CO₂ reduction products and a detailed categorical discussion of the means of modulation and modification of each copper-based catalyst. Finally, this review highlights the existing challenges and proposes future research directions in the development of copper-based photocatalysts for CO₂ reduction, focusing on boosting energy utilization and improving product formation rates.
