| 英文摘要 | Co oxidation is a widely used model system for understanding fundamental aspects of heterogeneous catalysis. while platinum (pt) continues to be a reference material for co oxidation catalysis, poisoning of pt catalysts presents a critical issue that blocks reaction sites and impedes subsequent reaction steps. fabrication of co poison-free pt catalysts remains a great challenge due to its co-philic nature. herein, we report a pt based catalyst to effectively tackle co poisoning by tightly anchoring pt sub-nanoclusters onto mn-mullite oxide (smmn2o5) via atomic layer deposition. superior co oxidation activity has been observed with a significantly lowered light-off temperature and apparent activation energy. in situ diffuse reflectance infrared fourier transform spectroscopy analysis, oxygen isotope experiments and density functional theory calculations confirm that the low-temperature activity originates from active oxygen atom sources at the bifunctional interface structure. |
