Catalyzing a cleaner future: recent advancement in photocatalytic conversion for CO-to-solar fuels.

Photocatalytic CO conversion represents a groundbreaking approach to addressing two of the most pressing global challenges: mitigating CO emissions and producing sustainable fuels. This review article provides an in-depth summary of the achievements made in the last five years to enhance the efficiency and selectivity of CO photoreduction typically on photocatalytic materials (not including organic molecules or coordination compounds), with specific focus on producing high-value hydrocarbon fuels including methanol, ethanol, ethene, and ethane.
