Plasmonic ternary hybrid photocatalyst based on polymeric g-C3N4 towards visible light hydrogen generation.


ABSTRACT: Surface plasmon resonance (SPR) effect of noble metal nanoparticles (NPs) for photocatalysis has a significant enhancement. In this system, a plasmonic ternary hybrid photocatalyst of Ag/AgBr/g-C3N4 was synthetized and used in water splitting to generation H2 under visible light irradiation. 18%Ag/AgBr/g-C3N4 showed the highest photoactivity, with the efficiency of hydrogen generation as high as 27-fold to that of pristine g-C3N4. Compared to simple mixture of Ag/AgBr and g-C3N4, hetero-composite Ag/AgBr/g-C3N4 showed a higher photoactivity, even though they contained same content of Ag/AgBr. We find that significant factors for enhancing properties were the synergistic effect between Ag/AgBr and g-C3N4, and the light absorption enhancing by SPR effect of Ag NPs. Ag/AgBr NPs firmly anchored on the surface of g-C3N4 and their high dispersion were also responsible for the improved activity and long-term recycling ability. The structure of Ag/AgBr/g-C3N4 hybrid materials and their enhancement to photocatalytic activity were discussed. Meanwhile, the possible reaction mechanism of this system was proposed.
