太阳能驱动的二氧化碳转化为高附加值的化学品和能源丰富的燃料是解决全球变暖和解决能源供应危机的有前途的战略之一。尽管人们在探索各种均相和多相光催化剂方面付出了巨大的努力，但其电流效率和对有价值的化学物质的选择性仍然相当适中，因此希望开发具有优异选择性的高效光催化体系用于CO2还原。本文首先介绍了纯水光催化还原CO2的基本原理、反应体系和产物的可靠检测方法。从促进CO2吸附活化、加速水氧化动力学和调控电荷分离等方面综述了近年来光催化CO2还原技术的主要研究进展。最后展望了CO2光催化还原多相催化剂的精确设计及面临的挑战，指出了进一步开发具有高CO2转化效率和产物选择性的光催化体系的重要意义。
Solar driven CO2conversion into high-value-added chemicals and energy-rich fuels is one of the promising strategies to tackle global warming and to address the energy-supply crisis. Even though enormous effort has been devoted to exploring all sorts of homogeneous and heterogeneous photocatalysts, the current efficiency and more importantly selectivity to valuable chemicals are still rather moderate, thus it is desired to develop high-efficiency photocatalytic system toward CO2reduction with excellent selectivity. In this review, fundamental aspects of photocatalytic CO2reduction by pure water, the reaction systems and the reliable method for detection of the products are firstly described. Thereafter the recent advances of the main strategy for improving the photocatalytic CO2reduction from the perspective of promoting the CO2adsorption and activation, accelerating the kinetics of water oxidation, and modulating charge separation are overviewed. The prospects and challenges on precise designing heterogeneous catalysts for CO2photoreduction are proposed at the end, indicating the significance for the further development of photocatalytic systems with high CO2conversion efficiency and product selectivity.
