enhanced the photocatalytic activity of ammonia doped cus grown by hydrothermal route

Highly active cus nanoparticles (nps) were synthesized using a hydrothermal route with various sulphur ratios. the comprehensive characterization of these nps involved an analysis of their structure, composition, and optical properties, primarily conducted through x-ray diffraction (xrd) analysis. the xrd pattern confirmed the presence of the hexagonal phase in the cus particles. the investigation further determined an estimated bandgap energy of 3.80 ev for the slightly sulphur-rich cus nps. notably, this energy value exceeds that of bulk cus, indicating a noticeable miniaturization effect. the novel cus nps exhibited outstanding photocatalytic activity in the degradation of methyl red (mr), particularly under visible light. this impressive performance is attributed to surface-bound oh ions on the cus nanostructures, facilitating the adsorption and acceleration of the degradation process for mr molecules under visible light irradiation. the research highlights the significant promise and efficiency of the synthesized cus nps as photocatalysts. these nanoparticles are exceptionally responsive to stable visible light, making them highly suitable for purifying chemically contaminated wastewater. specifically, their effectiveness in degrading stable azo dyes, exemplified by mr, underscores their potential in practical applications.
