发现用于CO和CO2氢化成有价值的烃燃料和醇的改进的化学方法对于化学工业是至关重要的。这些技术有可能通过增加废物流的价值来减少人为二氧化碳排放，同时减少我们对化石燃料的消耗。目前可用于CO和CO2加氢的热催化技术在能量输入方面要求很高。目前正在开发各种替代技术用于考克斯加氢，其中太阳能驱动的二维（2D）和2D相关复合材料的工艺特别有吸引力，因为地球上太阳能丰富，并且在非常温和的反应条件下，缺陷工程2D材料对特定有价值的产品具有高选择性。本文综述了太阳能驱动的考克斯还原为碳氢化合物的2D材料的最新进展。2D催化剂性能的优化需要跨学科的研究，包括催化剂电子结构操纵和形态控制，表面/界面工程，反应器工程和密度泛函理论建模研究。通过提高对2D相关催化剂的结构-性能关系的理解，这是通过应用现代原位表征技术实现的，用于CO和CO2还原为高价值产品（如烯烃）的实用光/光热/光电化学技术可以在不久的将来实现。
The discovery of improved chemical processes for CO and CO2 hydrogenation to valuable hydrocarbon fuels and alcohols is of paramount importance for the chemical industry. Such technologies have the potential to reduce anthropogenic CO2 emissions by adding value to a waste stream, whilst also reducing our consumption of fossil fuels. Current thermal catalytic technologies available for CO and CO2 hydrogenation are demanding in terms of energy input. Various alternative technologies are now being developed for COx hydrogenation, with solar-driven processes over two-dimensional (2D) and 2D-related composite materials being particularly attractive due to the abundance of solar energy on Earth and also the high selectivity of defect-engineered 2D materials towards specific valuable products under very mild reaction conditions. This review showcases recent advances in the solar-driven COx reduction to hydrocarbons over 2D-based materials. Optimization of 2D catalyst performance demands interdisciplinary research that embraces catalyst electronic structure manipulation and morphology control, surface/interface engineering, reactor engineering and density functional theory modelling studies. Through improved understanding of the structure–performance relationships in 2D-related catalysts which is achievable through the application of modern in situ characterization techniques, practical photo/photothermal/photoelectrochemical technologies for CO and CO2 reduction to high-valuable products such as olefins could be realized in the not-too-distant future.
