Summary: Photocatalysis is effective in removing small molecules like anticancer drugs, with faster kinetic rates found at pH 5 and lower drug concentrations. However, the efficiency of photocatalysis can be reduced by the addition of inorganic salts and organic compounds. The degradation mechanism of the drugs involves hydroxyl radicals and singlet oxygen, with potential toxicity of newly formed products needing further study.

Summary: TiO2-Ag doped nanoparticulate (TiO2-Ag-NP) adhesive photocatalytic films were used to assess the ability to reduce indoor microbial particles. The films were applied in various living spaces and showed a reduction of microbial pollution by more than 70%. The correlation between the reduction of relative light unit (RLU) and colony forming units per cubic meter (CFU/m(3)) confirmed the efficacy of the TiO2-Ag-NP adhesive film in reducing microbial pollution.

Summary: This study developed a series of mesoporous TiO2 doped with polyoxometalates [H3PMo12O40] (PMo12) and loaded with Bi nanoparticles (NPs) composites through electrospinning/calcination and hydrothermal methods. The composites exhibited excellent and persistent photocatalytic activity for removing tetracycline (TC), enrofloxacin (EFA), and methyl orange (MO) under visible-light illumination. The photocatalytic mechanism was revealed, and the possible degradation pathways of TC were established. The design and preparation of low-cost, efficient, stable, and versatile photocatalysts were discussed, providing new insights for future research.

Summary: Biochar-modified TiO2 (C/TiO2) was prepared and showed improved photocatalytic performance for NH3-N removal from aqueous solutions. Characterization analyses confirmed the successful modification of biochar on TiO2 and the introduction of -COOH groups, which enhanced the photocatalytic performance. The composite C/TiO2 demonstrated a larger surface area and more pores, along with the presence of typical characteristic peaks of anatase-TiO2. NH3-N degradation mainly resulted in N-2 as the degradation product, indicating the potential of C/TiO2 for wastewater treatment and sewage sludge treatment.

Summary: This study investigated the potential of magnetic fluorescence hybrid nanoparticles for simultaneous detection and removal of Cu(II) ions and RhB dye degradation. The nanoparticles showed selective adsorption of Cu(II) ions and efficient degradation of RhB under UV light. The Langmuir isotherm model fit the adsorption data well, and the adsorption process was found to be endothermic, favorable, and spontaneous.

Summary: In this study, spherical zinc ferrite nanoparticles were prepared with uniform size and a band gap suitable for visible light absorption. Zinc doping enhanced the absorption of visible light and improved the separation of photogenerated carriers, resulting in effective photocatalytic degradation of CBZ. The material showed high removal efficiency and a pseudo first-order kinetics with a rate constant of 0.0367 min(-1). In-vitro and in-vivo toxicity of the nanoparticles were also examined for environmental implications.
