| 英文摘要 | Cobalt-manganese composite oxides have high-activity potential for catalytic oxidation of volatile organic compounds (VOCs). However, low defect content and poor oxygen mobility of the spinel structure make it difficult to efficiently activate C-H bonds of propane at low-temperature. Herein, novel amorphous Co-Mn binary oxides with enhanced defect were fabricated by a facile self-redox approach. Highly defective amorphous Co-Mn binary oxides with low-temperature reducibility, weak Mn-O bond strength and good mobility of the surface lattice oxygen remarkably improved the catalytic activity for propane oxidation. Highly defective amorphous Co1Mn3Ox catalyst showed the best catalytic activity for propane mineralization and the T-90 was 207 degrees C under high space velocity (18 000 mL.g(-1) h(-1)). Moreover, in situ spectroscopy technologies were utilized to explore the structure-activity relationship and the degradation mechanism of propane oxidation under real reaction condition. Significantly, as an effective defect engineering strategy, amorphous binary oxides exhibit excellent activity and can provide some enlightenments for developing efficient VOCs catalysts. |
