Abstract Due to concerns about the accessibility of clean water and quality treated wastewater, developing a suitable solution enhance is critical. Thus, current study focused on synthesis cadmium-doped CdIn 2 S 4 incorporated in chitosan, forming Cd/CdIn @Ch quantum dots using solvothermal technique for efficient photodegradation hazardous pollutants like ofloxacin para-nitrophenol through H O -mediated AOP. were characterized by several advanced methods, including XRD, PL, UV-DRS, FTIR, SEM, HR-TEM, XPS, DSC, TGA, EDX, Elemental mapping analysis. The influence varying reaction parameters, such as effect organic compounds, inorganic ions, matrices, was also investigated. prepared composite showed outstanding efficiency 85.51 ± 1.35% 96.70 1.31%, with rate constant 0.02334 0.15134 min −1 , which 1.24 2.07 times higher than pristine para-nitrophenol, respectively. COD values reduced 80.67 1.67% 88.36 1.43% whereas TOC 73.49% 86.34%, respectively, from their initial values. improved performance ascribed encapsulation leading self-doping cadmium into photocatalyst, doping site can generate local electron accumulation point, improving charge separation efficacy surface mitigation capability chitosan nanosheets even further. scavenger experiments that hydroxyl superoxide radicals played significant part contaminants. Additionally, excellent constancy recyclable up six times, suggesting exceptional stability reusability manufactured photocatalyst. fabricated could be an photocatalyst removing wastewater near future.

Abstract Herein, a binary nanocomposite CdS/CeO 2 has been fabricated via one-pot co-precipitation method for the degradation of Rose Bengal (RB) dye. The structure, surface morphology, composition, and area prepared composite were characterized by transmission electron microscopy, scanning X-ray powder diffraction, photoelectron spectroscopy, Brunaur–Emmett–Teller analysis UV–Vis diffuse reflectance spectroscopy photoluminescence spectroscopy. (1:1) particle size 8.9 ± 0.3 nm 51.30 m /g. All tests indicated agglomeration CdS nanoparticles over CeO . showed excellent photocatalytic activity in presence hydrogen peroxide under solar irradiation towards Bengal. Near to about complete 190 ppm RB dye could be achieved within 60 min optimum conditions. enhanced was attributed delayed charge recombination rate lower bandgap photocatalyst. process found follow pseudo-first-order kinetics with constant 0.05824 −1 sample stability reusability maintained 87% efficiency till fifth cycle. A plausible mechanism is also presented based on scavenger experiments.
