One-step synthesis of rod-on-plate like 1D/2D-NiMoO/BiOI nanocomposite for an efficient visible light driven photocatalyst for pollutant degradation.

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.

Complete photocatalytic degradation of tetracycline by carbon doped TiO supported with stable metal nitrate hydroxide.

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.

Revealing the stability of CuWO/g-CN nanocomposite for photocatalytic tetracycline degradation from the aqueous environment and DFT analysis.

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.

Construction of S-scheme 1D/2D rod-like g-CN/VO heterostructure with enhanced sonophotocatalytic degradation for Tetracycline antibiotics.

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.

Complete removal of Tetracycline by sonophotocatalysis using ultrasound-assisted hierarchical graphitic carbon nitride nanorods with carbon vacancies.

Tuning a graphitic carbon nitride (CN) structure is an effective strategy to advance its physicochemical and electronic properties. Herein, hierarchical CN nanorods with carbon vacancy were synthesized via ultrasound-assisted thermal polycondensation method wherein melamine-HONH·HCl complex acts as a template. The hierarchical CN nanorods can facilitate multiple light scattering, provide large specific surface area with extensive reactive sites and endow abundant mass-transport channels for charge migration.

rGO supported self-assembly of 2D nano sheet of (g-CN) into rod-like nano structure and its application in sonophotocatalytic degradation of an antibiotic.

Graphitic carbon nitride (g-CN) is an analog of graphite due to its unique electronic structure. g-CN based materials have been used in photocatalytic applications. However, pure g-CN suffers from major shortcomings which include poor disparity, low surface area and a high recombination rate of photo generated electron-hole pairs that significantly reduce its photocatalytic activity.

Reduced graphene oxide (rGO) supported electron deficient B-doped TiO (Au/B-TiO/rGO) nanocomposite: An efficient visible light sonophotocatalyst for the degradation of Tetracycline (TC).

Incorporation of electron deficient boron atoms along with Au doped TiO in the presence of rGO support was synthesized by hydrothermal method and demonstrated for the sonophotocatalytic degradation of TC under visible light illumination. The successful incorporation of electron deficient boron atoms and Au on TiO was considerably enhanced the optical absorption towards visible region due to the formation acceptor energy levels below to the conduction band of TiO by boron doping and surface plasmonic effect of Au. Moreover, formation of acceptor energy levels and introduction of reduced graphene oxide (rGO) support significantly improved the electron-hole pair separation and transportation which were supported by UV-vis-DRS, photo-current and photoluminescence measurements.
