The increasing presence of pharmaceutical contaminants, such as paracetamol, in water sources necessitates the development efficient and sustainable treatment technologies. This study investigates photocatalytic degradation mineralization paracetamol under visible light using nickel-doped titanium dioxide (Ni–TiO2) catalysts synthesized via sol-gel method. were characterized through Raman spectroscopy, UV–Vis diffuse reflectance spectroscopy (UV–Vis DRS), surface area measurements. Ni doping enhanced absorption TiO2, reducing its band gap from 3.11 eV (undoped) to 2.49 at 0.20 wt.% loading, while analysis confirmed incorporation with anatase predominant phase. Ni(0.1%)-TiO2 catalyst exhibited highest activity, achieving 88% total organic carbon (TOC) removal (5 ppm) after 180 min optimal conditions (catalyst dosage, 3 g L−1). Stability tests demonstrated 84% retained efficiency over five cycles, a kinetic rate constant 0.010 min−1. Hydroxyl radicals identified main reactive species. maintained high performance tap water, 78.8% TOC removal. These findings highlight potential cost-effective, light-active photocatalyst for pollutants, promising scalability industrial applications.

Ternary g-C3N4/CQD/Ag photocatalysts were synthesized via deposition of carbon quantum dots (CQDs) and silver nanoparticles (Ag) onto graphitic nitride (g-C3N4) for efficient acetaminophen degradation. The nanocomposites exhibited enhanced photoresponse broad-spectrum photocatalytic activity under both UV (254 nm, 250 W) Xenon (>420 500 irradiation. Characterization by XRD, FTIR, SEM, PL, EDX elucidated the material’s composition, structure, morphology, optical properties. Optimized degradation (50 mg/L) was achieved at pH 7 with 0.6 g/L catalyst loading 60 min irradiation, yielding efficiencies 87.5% (UV) 85.3% (Xenon). Radical quenching experiments GC-MS analysis identified hydroxyl radicals as primary reactive species revealed a gradual decrease in intermediate toxicity during mineralization. This study demonstrates superior performance ternary compared to binary systems effective removal.

A single-atom catalyst is a supported material in which the active phase presented as isolated atoms. Single atom photocatalytic degradation of micropollutants has garnered significant attention recent research. However, updated their performance still limited. This review paper presents key aspects related to use SACs micropollutant degradation: The influencing factors like structure, surface area, density, relative humidity, temperature airflow, light intensity and reactants concentrations are also discussed. Further synthesis methods including atomic deposition, ball milling, trapping, pyrolysis, two steps doping, wet impregnation, facile electrostatic adoption updated. Characterization techniques STEM, TEM, FTIR, XAS, XRD, XPS, DFT evaluated relation quality with an emphasis on performances destruction well applications. catalysts endowed uniform, definite metal centers tunable matching options, give them excellent vigor special selectivity for defined In addition, mechanism harvesting, charge transfer separation, applications single micropollutants, photocatalysts support combinations other materials technologies challenges stability recyclability, loading, nature carrier, structure future perspective Finally highlighted conclusion remarks keynote areas.
