Visible Light Induced Photocatalytic Degradation of Diclofenac in Aqueous Solution Using Fabricated ZnO/g-CN by Facile Calcination Technique.

The ability of the heterojunction between two distinct semiconductors with appropriately matched band gaps to improve the separation of photogenerated electron-hole pairs has been demonstrated to enhance photocatalytic activity. Hence, ZnO/g-CN composites have been fabricated by the facile deposition and calcination of ZnO and g-CN. X-ray photoelectron spectroscopy, powder X-ray diffraction, and Fourier transform infrared spectroscopy confirm the formation of the composite.

Purification of aqueous orange II solution through adsorption and visible-light-induced photodegradation using ZnO-modified g-CN composites.

Semiconductor-based remediation enables environmentally friendly methods of removing aqueous pollutants. Simply fabricated ZnO modified g-CN composites were utilized as bifunctional adsorptive photocatalysts for orange II removal from aqueous solution through adsorption and photocatalysis processes. The adsorption isotherm data of the g-CN (g-CN) and ZnO modified g-CN (ZCN) composites on orange II solution were better fitted with the Langmuir isotherm compared to the Freundlich isotherm.

Black Phosphorus-Doped Graphitic Carbon Nitride with Aromatic Benzene Rings for Efficient Photocatalytic Hydrogen Production.

Graphitic carbon nitride (g-CN, abbreviated as g-CN) suffers from low visible-light-responsive photocatalytic efficiency. In this study, aromatic benzene rings and black phosphorus (BP) were successfully incorporated into g-CN photocatalysts (BP/A-CN), resulting in modified materials with improved properties. Structural analysis confirmed the successful integration of aromatic rings and BP into the g-CN framework, indicating the formation of a stable composite.

One-Step Fabrication of the ZnO/g-CN Composite for Visible Light-Responsive Photocatalytic Degradation of Bisphenol E in Aqueous Solution.

The ZnO/g-CN composite was successfully synthesized by a simple one-step calcination of a urea and zinc acetate mixture. The photocatalytic activity of the synthesized composite was evaluated in the degradation of bisphenol E (BPE). The morphology, crystallinity, optical properties, and composition of the synthesized composite were characterized by using various analytical techniques such as scanning electron microscopy (SEM), transmitted electron microscopy (TEM), field emission-electron probe microanalysis (FE-EPMA), nitrogen adsorption and desorption isotherm measurement, Fourier-transform infrared (FTIR) spectroscopy, X-ray powder diffraction (XRD), diffuse reflectance spectroscopy (DRS), photoluminescence (PL) spectroscopy, electrochemical impedance spectroscopy (EIS), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA).
