【摘要】 光催化利用太阳光这一可再生能源，通过将二氧化碳转化为CO、CH₄、CH₃OH和C₂H₅OH等有用的太阳能燃料,为解决全球变暖和能源短缺问题提供了一种潜在的解决方案。在已研究过的各种方案中，铜基光催化剂因其成本效益高且比贵金属催化剂更为丰富，在二氧化碳转化方面尤其具有吸引力。本文献综述全面总结了用于二氧化碳还原反应的铜基光催化剂的最新发展，包括金属铜、氧化铜和氧化亚铜光催化剂。综述还对二氧化碳还原产物进行了分类总结，并对每种铜基催化剂的调制和改性方法进行了详细分类讨论。最后，本综述强调了铜基光催化剂在二氧化碳还原方面的现有挑战，并提出了未来的研究方向，重点是提高能量利用率和产品形成率。更多还原

【Abstract】 Utilizing sunlight as a renewable energy source,photocatalysis offers a potential solution to global warming and energy shortages by converting CO₂ into useful solar fuels,including CO,CH₄,CH₃OH,and C₂H₅OH.Among the various formulations investigated,copper-based photocatalysts stand out as particularly appealing for CO₂ conversion due to their cost-effectiveness and higher abundance in comparison to catalysts based on precious metals.This literature review provides a thorough summary of the latest developments in copper-based photocatalysts used for CO₂ reduction reactions,including metallic copper,copper oxide,and cuprous oxide photocatalysts.The review also provides a categorical summary of the CO₂ reduction products and a detailed categorical discussion of the means of modulation and modification of each copper-based catalyst.Finally,this review highlights the existing challenges and proposes future research directions in the development of copper-based photocatalysts for CO₂ reduction,focusing on boosting energy utilization and improving product formation rates.更多还原
