The visible light active ternary composite AgI/AgCl/h-BN was synthesized via water-soluble KCl crystal temple and ion-exchange process using h-BN nanosheets as the catalyst support.The structure and morphology of as-prepared samples were characterized by XRD, FT-IR, SEM and TEM.The absorption properties of the samples were analyzed by UV-Vis DRS.The result of photocatalytic degradation rate of RhB can reach 93% after 24 min illumination under visible light, indicating that the higher photocatalytic activity and stability of AgI/AgCl/h-BN than bulk AgCl, AgCl cubes, AgI/AgCl nanocashews and that reported in the literature.And the degradation rate of RhB kept almost unchanged after 4 cycles, which indicated AgI/AgCl/h-BN photocatalyst excellent stability.Furthermore, the proposed mechanisms for the enhanced photocatalytic and stability were investigated by photoelectron chemical measurements, radical trapping experiments and ESR analysis.
