Solar-energy-driven photocatalysis, such as photocatalytic reduction of CO2, is promising simultaneously for the energy and environmental issues. Coating thin carbon layers with the thickness less than 10 nm on photocatalysts has been developed as an efficient strategy for enhancing the photocatalytic efficiency in recent years. In the present review, we summarize the crucial progress on carbon-coated photocatalysts. Origins for the improved light absorption, charge separation, reactant adsorption and photocatalytic stability on carbon-coated photocatalysts as well as the applications of carbon-coated photocatalysts are discussed. Future opportunities and challenges associated with carbon-coated photocatalysts are shown at the end of the review. We hope that the present review can trigger more deep insights on carbon-coated photocatalysts and provide new opportunities for developing low-cost but efficient photocatalysts.
