As a “kill two birds with one stone” approach, photocatalytic CO₂ reduction to solar fuels can save supplying energy and simultaneously protect our environment. Specifically, the use of CO₂ as the starting carbon source can help with the required emission cuts. Meanwhile, it directly generates short-chain hydrocarbon products such as CH₄, CH₃OH, C₂H₆ and so on, which can serve as a renewable energy source (solar fuels) to alleviate the increasingly tense energy crisis. Two-dimensional (2D) nanomaterials possess several extraordinary advantages, including large surface-to-volume ratio, abundant active sites, atomic thickness, and a high fraction of coordinated unsaturated surface sites, making them promising candidates with high photocatalytic activity for CO₂ reduction. This review summarizes a series of typical 2D nanomaterials for photocatalytic CO₂ conversion, such as graphene-based photocatalysts, graphitic carbon nitride-based photocatalysts, 2D metal oxide-based photocatalysts, 2D metal chalcogenide-based photocatalysts, 2D metal oxyhalide-based photocatalysts, and layered double hydroxide-based photocatalysts. Furthermore, based on the characteristics of 2D materials and the current status of research on photocatalytic CO₂ reduction, the challenges and opportunities of 2D materials as prospective photocatalysts for CO₂ reduction will also be discussed.

二维纳米材料，用于光催化还原CO ₂为太阳能

作为“用一只石头杀死两只鸟”的方法，将光催化还原CO ₂转化为太阳能可以节省能源供应，同时保护环境。具体而言，使用CO ₂作为起始碳源可以帮助减少所需的排放量。同时，它直接生成CH ₄，CH ₃ OH，C ₂ H ₆等短链烃产物。等等，它们可以用作可再生能源（太阳能）以缓解日益紧张的能源危机。二维（2D）纳米材料具有许多非凡的优点，包括大的表面体积比，丰富的活性位点，原子厚度以及高比例的配位不饱和表面位点，使其成为具有高光催化活性的CO ₂还原候选材料。这篇综述总结了一系列用于光催化CO ₂的典型二维纳米材料转换，例如基于石墨烯的光催化剂，基于石墨氮化碳的光催化剂，基于2D金属氧化物的光催化剂，基于2D金属硫属化物的光催化剂，基于2D金属氧卤化物的光催化剂和基于双氢氧化物的层状光催化剂。此外，基于二维材料的特性和研究上的光催化CO的当前状态₂还原，2D的材料作为用于CO准光催化剂的挑战和机遇₂减少也将被讨论。
