One-pot synthesis of large-scaled Janus Ag–Ag2S nanoparticles and their photocatalytic properties

Abstract

We report a facile, one-pot route based on thermal decomposition of a single molecular precursor for preparing spherical, eggplant-shaped Janus Ag–Ag2S nanoparticles; these Ag–Ag2S Janus-coupled P25 TiO2 composites show a higher photocatalytic efficiency than those of the Ag2S NPs coupled P25 TiO2 composites and pure P25 TiO2.
