Abstract
Hybrid nanostructures comprising plasmonic noble metal and semiconductor have attracted attention owing to their novel properties and potential applications. However, the facile synthesis of these hybrid nanostructures with well-defined heterostructures and high porosity still remains challenging. Herein, we report a facile method for preparing porous triangular Au-Ag-Ag2S bimetal-semiconductor hybrid nanostructures. Following the selective etching of Ag in the Ag-Ag2S hybrid nanostructures, Au was deposited in a controlled manner. Using triangular Ag-Ag2S hybrid nanoplates with new heterostructures as templates and introducing an additional reducing agent in the galvanic replacement reaction with HAuCl4, the prepared Au-Ag-Ag2S had a porous structure, with plasmonic nanocavities on their surfaces and high absorbance in the visible and near-infrared regions. These hybrid nanostructures exhibited enhanced catalytic performance and very high photothermal conversion properties.
