Method for enhancing catalytic performance of silicon carbide film material through acid etching
The invention relates to a method for enhancing the catalytic performance of a silicon carbide film material through acid etching. According to the method, the catalytic performance of the SiC film material can be remarkably enhanced only by immersing the SiC film material in an acid solution for a certain time and then drying the SiC film material. According to the method, the characteristic of acid corrosion resistance of the SiC film material is utilized, so that an acid solution only etches catalytic components in the SiC film material, and the structure of the SiC film material is not damaged. The SiC catalytic membrane subjected to acid etching can efficiently intercept dust and catalytically degrade gas-phase pollutants such as nitrogen oxides and VOCs, and has a wide application prospect in the field of air pollution control.
本发明涉及一种酸刻蚀增强碳化硅膜材料催化性能的方法，该方法仅需将SiC膜材料浸没在酸溶液中一定时间然后干燥即可显著增强SiC膜材料的催化性能。该方法利用了SiC膜材料耐酸腐蚀的特性，使得酸溶液仅对SiC膜材料中的催化组分进行刻蚀，而不会破坏SiC膜材料的结构。酸刻蚀后的SiC催化膜能够在高效截留粉尘的同时对氮氧化物、VOCs等气相污染物进行催化降解，在大气污染治理领域具有广阔的应用前景。
