Synthesis and Photocatalytic Applications of Silver Sulfide Nanostructures: Recent Advancement

Abstract

Silver sulfide nanoparticles belong to the family of important metal chalcogenides. Silver sulfide has been extensively studied in recent years due to its applications in various fields ranging from biosensors, infrared detectors, and optoelectronics to catalysis. Silver sulfide is considered as a potential photocatalyst due to narrow band gap energy, mechanical and thermal stability, cyclability, and ease of synthesis. Different methods have been investigated to produce various forms of silver sulfide nanoparticles. The present chapter focuses on the recent progress in synthesis of silver sulfide nanoparticles using hydrothermal method, chemical bath deposition, microwave-based approach, sonochemical method, single molecular precursor’s decomposition, and green synthesis. Moreover, the application of silver sulfide nanoparticles in photocatalytic degradation of organic dyes is discussed in details.
