Preparation of cadmium sulfide inverse opal photonic crystal

Controllable synthesis of cadmium sulfide inverse opal structure photonic crystal film, nanocrystals modified with thioglycolic acid and P (St-MMA-SPMAP) polymer beads were co-assembled, and the inverse opal structure was successfully constructed and used for visible light photolysis. Hydrogen production from aquatic. The results show that under visible light (λ≥420 nm), the photodegradation of Cd S-310 inverse opal structure film has doubled the performance of photodegradation and hydrogen production of cadmium sulfide nanoparticles. This is mainly due to the hierarchical pore structure inverse opal The characteristics of photonic crystals improve the photocatalytic performance of the catalyst: First, the periodic structure of inverse opal increases the propagation of photons in the material and improves the utilization rate of sunlight by the catalyst; at the same time, the walls of macropores are stacked by nanoparticles It provides more reactive sites in the reaction; in addition, the pore structure is conducive to the transport of substances and the adsorption of molecules.
