제목 Preparation of Porous Triangular Au–Ag–Ag2S Hybrid Nanostructures and Their Applications
초록 In this study, we report a facile approach to obtain bimetallic and semiconductor hetero-nanostructures through galvanic replacement reaction. Ag–Ag2S nanoparticles had robust structures and they maintained their initial structures through the final state of galvanic replacement reaction, leaving nanoframe structures of Au–Ag–Ag2S. The hybrid Ag–Ag2S nanoplates were further treated with co-reduction assisted galvanic replacement reaction by introducing a mild reducing agent of hydroquinone and producing highly porous structures of ternary Au–Ag–Ag2S hybrid nanoparticles. A remarkable increase of catalytic reduction of 4-nitrophenol and photothermal performance was occurred for triangular porous Au–Ag–Ag2S nanoparticles due to the synergistic effects and the advantages of well-defined structures.
