Low-Temperature Synthesis of BiS Hierarchical Microstructures via Co-Precipitation and Digestive Process in Aqueous Medium.

Bismuth sulfide (BiS) nanostructures have gained significant attention in the fields of catalysis, optoelectronics, and biomedicine due to their unique physicochemical properties. This paper introduces a simple and cost-effective method for producing BiS microstructures at low temperatures (25 and 70 °C). These microstructures are formed by the hierarchical self-assembly of BiS nanoparticles, which are typically 15-40 nm in size.
