Abstract
The large scale, ultrathin and (0 0 1) facet exposed anatase two-dimensional (2D) graphene-like TiO2 nanosheets were synthesized by hydrogen-bonding-mediated. The products were employed as scaffolding and deposited Ag@AgCl nanoparticles. The crystalline phase, morphologies and optical properties of as-prepared sample were surveyed. The results indicated that the as-prepared TiO2 nanosheets only have few nanometers thick. The Ag@AgCl nanoparticles were also successfully introduced into the surface of TiO2 nanosheets. By the modified of Ag@AgCl and significant enhanced the absorption spectrum in the visible light region. To assess the photocatalytic activities of as-prepared samples, the methylene blue (MB), methyl orange (MO) and rhodamine B (RhB) were employed to simulate the pollutants. The Ag@AgCl/TiO2 exhibited excellent photocatalysis under solar irradiation. There results suggested that, Ag@AgCl/TiO2-0.6 photocatalyst has suitable size of Ag@AgCl particles, large surface areas, abundant surface active sites and effective photogenerated electron-hole pair's separation, which significant improve the photocatalytic activities.
