外文摘要：Spinel oxide(NiCo2O4)has demonstrated great potential to replace noble metal catalysts for the oxidation reaction of air pollutants.To further boost the oxidation ability of such catalysts,in this study,a facile surface-engineering strategy wherein NiCo2O4was treated with different alkali solvents was developed.The obtained catalyst(NiCo2O4-OH)showed a higher surface alkalinity and more surface defects compared to the pristine spinel oxide,including enhanced structural distortion as well as promoted oxygen vacancies.The propane oxidation ability of NiCo2O4-OH was greatly enhanced,with a propane conversion rate that was approximately 6.4 times higher than that of pristine NiCo2O4 at a reaction temperature 193 ℃.This work sets a valuable paradigm for the surface modulation of spinel oxide via alkali treatment to ensure a high-performance oxidation catalyst.
