Formaldehyde degradation catalyst and preparation method thereof

The invention provides a formaldehyde degradation catalyst and a preparation method thereof. The catalyst is formed by compounding 0.1 to 0.5 percent by mass of nanogold and 0.1 to 0.5 percent by mass of nano platinum which are loaded into a porous matrix, wherein the porous matrix is a covalent organic porous polymer COP-4. By taking the covalent organic polymer as a carrier and taking precious metal, namely the nanogold and the nano platinum as active components, the active components are highly dispersed on a porous carrier to efficiently catalyze the degradation of formaldehyde while adsorbing the formaldehyde at room temperature, and therefore the air detergency to the formaldehyde is effectively improved. 本发明提供的种甲醛降解催化剂及其制备方法，催化剂主要由质量分数为0.1％～0.5％的纳米金和0.1％～0.5％的纳米铂负载于多孔基体中复合而成，其中，多孔基体为共价有机多孔聚合物COP?4。从而通过以共价有机聚合物为载体，以贵金属纳米金和纳米铂为活性组分，活性组分在多孔载体上高度分散，以用于在室温下吸附甲醛的同时高效催化降解甲醛，从而有效提高对甲醛的空气净化力。
