代表性研究工作

钒氧化物的还原性能调控及其高效活化乙苯及丙烷C-H键的研究（Angew. Chem. Int. Ed., 2023, 62, e202310062）：如下图所示，基于溶解-沉积平衡原理，开发了一种普适性的氨水后处理策略，成功实现了负载型金属氧化物还原性能的精准调控。通过该方法制备的VO_x-Al₂O₃催化剂在CO₂氧化乙苯脱氢和丙烷脱氢反应中表现出优异的催化性能。结合原位紫外-可见漫反射光谱、瞬态产物分析等表征技术，揭示了VO_x还原性能与其催化乙苯及丙烷C-H键活性之间的构效关系，并证实了H₂生成是丙烷脱氢反应的速控步骤。该研究为理解金属氧化物催化剂的构效关系提供了新的视角。

PtSn/CeO₂催化CO₂氧化丙烷脱氢制丙烯反应机理的研究（Nano Res., 2023, 16, 6237-6250）：构建了PtSn-CeO₂双功能催化体系，其中PtSn合金负责丙烷C-H键活化，而CeO₂载体负责强化CO₂吸附活化。如下图所示，通过调控Sn/Pt摩尔比，深入研究了Sn修饰对Pt/CeO₂催化剂在CO₂氧化丙烷脱氢反应中活性及丙烯选择性的影响规律。综合运用原位拉曼光谱、瞬态产物分析等表征手段，结合反应性能评价结果，证实了PtSn/CeO₂催化CO₂氧化丙烷脱氢遵循氧化还原机理，并确定Sn修饰的Pt-O-Ce界面为催化活性中心。该研究在原子/分子尺度上阐明了CO₂氧化丙烷脱氢的活性中心结构特征与反应机制。
