A critical review on In2S3-based nanomaterial for emerging contaminants elimination through integrated adsorption-degradation technique: Effect of reaction parameters and co-existing species

Abstract

The possibility of combined adsorption-degradation processes in wastewater treatment using nanomaterials based on indium sulfide (In₂S₃) is examined in this review paper. Regarding the synergistic adsorption and degradation of pollutants, In₂S₃ performs exceptionally well, making it a suitable choice for wastewater remediation. Insights have been given to the pollutant removal mechanism through this integrated technique. The synergistic removal process is affected by several operational factors, including pH, catalyst dose, pollutant concentration, and contact duration. This analysis highlights the significance of optimizing these parameters for optimal contaminant removal efficiency. The influence of co-existing species, including cations, anions, and organic compounds, on the integrated elimination process is further highlighted by a discussion of their role. Future research directions are suggested, including a better comprehension of underlying processes, investigation of hybrid nanocomposites, and evaluation of long-term stability and recyclability to enhance the applicability of In₂S₃-based nanomaterials. This study aids in the creation of effective and long-lasting wastewater treatment methods by using the potential of In₂S₃-based nanomaterials.
