PHOTOCATALYST AND APPLICATION THEREOF IN PHOTOCATALYTIC ENVIRONMENTALLY-FRIENDLY TREATMENT OF POWER BATTERIES

Disclosed are a photocatalyst and application thereof in environmentally friendly photocatalytic treatment of a power battery. The photocatalyst is obtained by loading Ag-TaON on a hollow glass microsphere, wherein a mass ratio of the Ag-TaON to the hollow glass microsphere is 1: 5 to 10. According to the invention, the Ag-TaON and the hollow glass microsphere are compounded, the hollow glass microsphere has better light permeability, which avoids mutual shielding between catalysts, such that the photocatalyst filled in a reactor is fully excited, which is capable of effectively improving a light utilization rate, thus improving the catalytic conversion efficiency of the photocatalyst.
