缺陷工程MOF锚定Cu位点实现CO2协同光重整，将生物基多元醇近乎全部转化为C1产物
Carbon Dioxide Synergized Photo‐Reforming for Efficient Valorization of Bio‐Polyols With a Dynamic Carbon Balance
AI 导读
研究构建了一种“自供给”光催化体系，将甘油氧化与CO2光还原耦合，用缺陷工程MOF锚定原子级分散的Cu位点，同时活化甘油和O2，并引入CO2调控活性氧物种的演化。
推荐理由
该工作把甘油氧化与CO2光还原耦合在同一催化体系中，使碳原子全部进入C1产物，为生物基多元醇的碳保留提供了一条可参照的反应设计思路。
创新点
将CO2从副产物重新定位为反应调节剂，通过CO2配位原位Cu I位点调控活性氧物种与C–C断裂路径，在动力学上匹配CO2释放与原位还原，从而同时突破氧化深度与碳保留之间的传统权衡。
