MoS2-gC3N4 encapsulated in nitrogen-doped graphene oxide: an efficient visible light photocatalyst for removal of Cr (VI) from aqueous solution and mineralization of organic contaminant

In response to the pressing environmental challenges posed by industrial wastewater laden with chromium (Cr) and neonicotinoid insecticides such as thiamethoxam (THM), this study embarks on a rigorous exploration of advanced photocatalytic methodologies. With a focus on mitigating the adverse impacts of Cr (VI) and THM, notorious for their deleterious effects on ecosystems and human health, the research endeavours to harness the synergistic potential of cutting-edge materials. Through meticulous synthesis and characterization, nitrogen-doped graphene oxide encapsulated MoS₂-gC₃N₄ emerges as a pivotal component in our novel photocatalytic system. This innovative composite exhibits exceptional visible light photocatalytic efficacy, demonstrating remarkable proficiency in pharmaceutical mineralization and Cr (VI) reduction in aqueous environments. By elucidating intricate mechanisms and optimizing operational parameters, this study contributes substantively to environmental remediation while emphasizing the importance of advanced materials and techniques in addressing contemporary challenges.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
