中文摘要：全球变暖对人类的生产生活造成了严重的威胁,已成为当今世界面临的重大挑战之一.碳中和这一重要举措能够有效缓解全球变暖的进程,在这一背景下光催化CO2还原可有效减少碳排放且促进碳循环.g-C3N4因其制备工艺简单、稳定性高、能带位置适宜以及优异的光催化性能而备受关注.因此,提高g-C3N4光催化CO2还原效率是当前研究的热点问题.本文重点探究了碳中和对于全球生态平衡和环境可持续发展的重要性以及在碳中和背景下g-C3N4光催化CO2还原的重要作用和发展前景;综述了目前解决限制g-C3N4光催化CO2还原瓶颈问题的方法和技术手段.对g-C3N4在光催化CO2还原领域存在的问题进行讨论,提出了未来的研究方向,并进行展望.本综述旨在为碳中和背景下基于g-C3N4催化剂光催化CO2还原的应用提供理论支持,为基于g-C3N4高效CO2还原光催化剂的设计提供思路.

外文标题：Progress and challenges of photocatalytic reduction of CO2 with g-C3N4-based photocatalysts in the context of carbon neutrality

外文摘要：Global warming has seriously threatened the industrial/agricultural productions and human life and has become one of the major challenges facing the world today.Carbon neutrality is an important measure for mitigating the greenhouse effect,and photocatalytic CO2 reduction can ef-fectively reduce carbon emissions and promote the carbon cycle.g-C3N4 has attracted much attention due to its simple preparation process,high stability,suitable energy band po-sition,and excellent photocatalytic performance;thus,im-proving its efficiency in photocatalytic CO2 reduction has become the focus of current research.The importance of carbon neutrality for the global ecological balance and en-vironmental sustainability and the important role and devel-opment prospects of g-C3N4 photocatalytic CO2 reduction in the context of carbon neutrality are the main focuses of this review.The current methods and technical means to solve the difficulty of the g-C3N4 photocatalytic CO2 reduction are summarized.The possible problems in the field of g-C3N4 photocatalytic CO2 reduction are discussed,and future re-search directions are proposed.The aim of this work is to provide theoretical support for the practical applications of g-C3N4 photocatalytic CO2 reduction and to present potential design concepts for efficient g-C3N4-based photocatalysts.
