其中催化氧化技术是利用催化剂活化氧气来彻底将甲醛转化为无毒无害的CO2

Among them, catalytic oxidation technology uses catalyst to activate oxygen to completely convert formaldehyde into non-toxic and harmless CO2 and H2O. At present, developing efficient catalysts and clarifying the reaction mechanism are the hotspots and difficulties in the research of formaldehyde catalytic oxidation. In this paper, Pt-based and Co-based catalysts were prepared by optimizing the conditions, respectively, and used in the catalytic oxidation of formaldehyde. The results showed that both types of catalysts showed excellent activity and stability. In addition, we also explored their reaction mechanism by characterization techniques such as in situ infrared, and elucidated that the microscopic environment around the catalyst's active center is crucial to their performance. certain ideas. The main research contents and results of this paper are as follows:
