Effect of La-doping on NiO photocatalyst for enhancing photocatalytic degradation performance under visible light irradiation: DFT calculations and degradation mechanism

Use of Natural Zeolite Clinoptilolite in the Preparation of Photocatalysts and Its Role in Photocatalytic Activity

“…NiO, a p-type semiconductor with a broad energy band gap of about 3.4-4.0 eV, is suitable for photocatalytic reactions [101][102][103]. However, its photocatalytic performance is restricted because of its limitations associated with poor adsorption performance and difficulties in the migration and separation of electron-hole pairs.…”

Enhancing the photocatalytic elimination of acephate residues using Ni0 doped and diatomite-supported NiO: optimization, pathway, and toxicity

“…NiO, a frequently investigated metal oxide-based photocatalyst, has demonstrated effective performance throughout the decomposition of soluble organic pollutants within aqueous environments. 35,36 NiO nanoparticles, along with their blends, possess distinct optical, chemical, physical, and thermal characteristics. 37,38 Consequently, structures made with NiO have been widely used in many fields as catalysts, dye-sensitized photocathodes, antibacterials, photo-electron equipment, and chemotherapy drugs.…”
