通过原位溶剂热法构建了富含氧空位的缺陷氧化钨(W₁₈O₄₉)/还原氧化石墨烯(rGO)复合光热催化剂。通过X射线衍射、扫描电子显微镜、X射线光电子能谱、紫外可见漫反射光谱等对复合催化剂的组成与结构进行了详细表征。在常压、不外加热源、光照下，W₁₈O₄₉/rGO复合光热催化剂具有优异的CO₂环加成反应活性，展现出最高95%的碳酸苯乙烯酯产率(173 mmol·g^-1·h^-1)，并在多次循环实验中具有不错的循环稳定性。上述结果表明rGO的引入扩充了W₁₈O₄₉/rGO复合光热催化剂的比表面积、提高其对CO₂的吸附容量、增加其光吸收和光生电荷传输效率，通过光催化与热催化的耦合作用显著提升了催化性能。

Photocatalytic CO₂ cycloaddition reaction presents a promising CO₂ conversion strategy to establish carbon neutrality. Among emerging catalysts, metal-organic frameworks (MOFs) have been regarded as paradigm-shifting photocatalysts for their atomic precision in active site engineering, controllable porosity, and exceptional photochemical stability under ambient conditions. However, inherent limitations persist in conventional MOFs, including restricted solar spectrum utilization, inefficient charge carrier separation, and inadequate epoxide activation ability. Recent breakthroughs address these challenges through multiple strategies: ligand engineering, dopant incorporation, and composite construction. This review systematically maps the evolutionary trajectory of MOF-based photocatalysts, providing mechanistic insights into structure-activity relationships and providing insights and directions for the design of high-performance MOF-based photocatalysts.
