A photocatalytic material for efficient photocatalytic removal of a high-concentration nitrate, and a preparation method and use thereof are disclosed. The preparation method includes the following steps: step 1: preparation of a citrate-stabilized silver nanoparticle; step 2: synthesis and functionalization modification of SiO.sub.2 step 3: preparation of Ag/SiO.sub.2; and step 4: preparation of an Ag/SiO.sub.2@cTiO.sub.2 core-shell structure. The photocatalytic material prepared by the present disclosure has high reduction catalytic activity and can quickly remove a high-concentration nitrate and achieve high nitrogen selectivity. In addition, due to protection of a titanium dioxide shell, the photocatalytic material has excellent stability and can remove a high-concentration nitrate in water when the nitrate coexists with a high-concentration chloride ion.

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.
