The compound is expected to be used for sewage treatment and active oxygen-based tumor treatment.

Description

technical field [0001] The present application relates to a ferrocene-functionalized nano-catalyst, a preparation method and application thereof, and belongs to the technical field of nano-catalysts. Background technique [0002] Nanocatalysts have received extensive attention in the field of catalysis due to their large specific surface area, high thermal stability, high activity and selectivity, and wide adaptability of raw materials. Studies have confirmed that as the particle size of nanoparticles decreases, the number of surface atoms will increase significantly. The tension is enhanced, making the surface atoms less stable and easier to bind to other atoms. Therefore, based on their nanostructures, nanocatalysts can practically improve the efficiency of catalytic reactions. However, combining multiple nanoparticles with catalytic properties into the same nanocatalyst can selectively improve the catalytic properties. [0003] The hydroxyl radical generated by Fenton ...
