采用沉淀法制备co3o4催化剂，用甲酸处理前驱体制备h - co3o4催化剂。研究了它们对N2O催化分解的催化活性。结果表明，h -Co3O4催化剂表现出比Co3O4更高的催化活性，这可能是由于h -Co3O4催化剂的BET表面积更大，特别是表面Co3+的量更多，增强了还原性，促进了氧的脱附能力。图形抽象
Co3O4catalyst was prepared by means of precipitation method and its precursor was treated with formic acid to prepare H-Co3O4catalyst. Their catalytic activities for N2O catalytic decomposition were studied. The results show that H-Co3O4catalyst exhibits much higher catalytic activity than Co3O4, which may result from the larger BET surface area, especially the more amount of surface Co3+, enhanced reducibility and promoted desorption ability of oxygen species.Graphical Abstract
