Synergistic photocatalytic activity of metal chalcogenides (MoS₂)-Modified Silver silicate (Ag₆Si₂O₇) nanocomposites for dyes degradation

A recent research focus aimed at enhancing photocatalysis efficiency by tackling rapid charge carrier recombination resulted in a significant breakthrough. Through the synthesis of a composite heterostructure comprising Ag₆Si₂O₇/MoS₂ using a hydrothermal approach, the creation of the AM-4 composite marked a notable advancement. AM-4 demonstrated remarkable photonic efficiency enhancements, achieving impressive degradation rates of 97.31% for rhodamine B and 98.31% for methylene blue within a mere 45-minute timeframe. Surpassing pure Ag₆Si₂O₇ by 26.65 times in rate constant, the superior performance of AM-4 was supported by a thorough examination of its physicochemical and electrochemical properties, reinforcing a proposed mechanism for its enhanced efficacy. Evaluation of its durability and reusability through XRD, BET, and XPS analyses further confirmed the composite's exceptional performance. This study deepens our comprehension of the Ag₆Si₂O₇/MoS₂ composite and offers valuable insights for advancing high-performance photocatalysis applications.
