Amorphous silicon oxide loaded monatomic cobalt catalyst as well as preparation method and application thereof

The invention discloses an amorphous silicon oxide loaded monatomic cobalt catalyst as well as a preparation method and application thereof, and relates to the technical field of organic waste gas treatment. According to the preparation method of the amorphous silicon oxide loaded monatomic cobalt catalyst, gaps of amorphous silicon oxide are generated in situ, abundant coordination bonds are coupled with aluminum atoms to form larger defect sites, cobalt atoms are riveted, and therefore the high-dispersion cobalt monatomic catalyst is obtained. The treatment effect of a persulfate system on volatile organic pollutants (VOCs) is effectively catalyzed and improved. The amorphous silicon oxide loaded monatomic cobalt catalyst is especially suitable for catalyzing and activating a persulfate system to degrade VOCs, and the degradation rate of the VOCs can reach 90% or above. 本发明公开了一种无定形氧化硅负载单原子钴催化剂及其制备方法和应用，涉及有机废气处理技术领域。本发明的无定形氧化硅负载单原子钴催化剂的制备方法是通过原位生成无定形氧化硅的间隙和丰富配位键与铝原子耦合形成更大的缺陷位以铆定钴原子从而得到高分散的钴单原子催化剂，有效催化提升过硫酸盐体
