The efficient conversion and utilization of abundant light alkanes and cheap lower alcohols are important and challenging research topics in chemistry.Photocatalysis brings a new opportunity for selective transformation of light alkanes and lower alcohols to produce high value-added chemicals under mild conditions.In this article,important research progresses in recent years are reviewed,which are focused on photocatalytic selective activation of C—H bond and C—C coupling of lower-carbon molecules to produce C2+ chemicals aiming at the light alkanes(i.e.,methane,ethane and propane)and lower alcohols(i.e.,methanol,ethanol and isopropanol).The key factors affecting the photocatalytic activity and selectivity and the fundamental issues related to C—H bond activation and C—C coupling are discussed.Future aspects in the research direction of photocatalytic transformation of lower-carbon molecules are presented.
