Visible light active 1D/2D-NiMoO/BiOI nanocomposite photocatalyst has been constructed by single step solvothermal method. Various compositions of NiMoO/BiOI nanocomposites are prepared by loading different amounts of nickel molybdate (NiMoO) (1, 2, 3 wt%) to the bismuth oxy iodide (BiOI) and investigated by XRD, FTIR, SEM, EDAX, TEM, UV-vis DRS, and PL analysis. Among the as-prepared photocatalysts, 1 wt% NiMoO incorporated BiOI (NMBI-1) showed superior photocatalytic activity with a rate constant of 0.

Article Synopsis
  • A new photocatalyst, BiOBr/BiYWO, was created using a one-pot hydrothermal method by varying KBr amounts (0.5 to 2.0 mmol) to improve its effectiveness under visible light.
  • The best-performing catalyst, made with 1.5 mmol of KBr, achieved a decomposition efficiency of 78.3% for methylene blue, with a low bandgap of 2.51 eV and better photoluminescence compared to others studied.
  • The catalyst exhibited stability and reusability over four cycles, highlighting its robust performance, and a proposed mechanism for methylene blue decomposition under light was also suggested.

Visible light-driven carbon-doped TiO supported with metal nitrate hydroxide (CT-Ni/Co/Cu) nanocomposites were prepared and characterized by various studies. It is fascinating to note that particle size of TiO was substantially reduced from 5 μm to 50 nm after doping of carbon which was confirmed by FESEM. Moreover, the incorporation of stable metal (Cu) nitrate hydroxide further enhanced the visible light absorption up to 800 nm as evident by UV-DRS.

Graphitic carbon nitride (g-CN) is an emerging metal-free photocatalyst, however, engineering the photocatalytic efficiency for the effective degradation of hazardous molecules is still challenging. An unstable and low bandgap CuWO was composited with g-CN to achieve synergistic benefits of tuning the visible light responsiveness and stability of CuWO. CuWO/g-CN nanocomposite exhibited a relatively high visible light absorption region and the bandgap was modified from 2.

Pharmaceutically active compounds are an emerging water contaminant that resists conventional wastewater treatments. Herein, the sonophotocatalytic degradation of Tetracycline (TC) antibiotics as a model contaminant was carried out over a rod-like g-CN/VO (RCN-VO) nanocomposite. RCN-VO nanocomposite was synthesized via ultrasound-assisted thermal polycondensation method.
