Enhancement of photocatalytic activity over NaBiO3/BiOCl composite prepared by an in situ formation strategy

Adsorption and degradation performance of Rhodamine B over BiOBr under monochromatic 532nm pulsed laser exposure

“…The UV-vis spectral variations also displayed an obvious wavelength shift of the band to shorter wavelengths. The wavelengths of the characteristic peaks were shifted from 554 nm to 548 nm under N 2 and 532 nm without N 2 bubbling, possibly because of the intermediate products of deethylated RhB molecules [27]. It should be noticed that no shift of the adsorption band at 554 nm was observed after the photolysis (or photocatalysis) and adsorption for 90 min (as depicted in Fig.…”

“…To date, several methods have been adopted for the solid-based band/electronic structure measurement and speculation, such as ultraviolet photoelectron spectroscopy (UPS) [28], flatband-potential-determination based photoeletrochemical techniques [29][30][31], atom's Mulliken electronegativity theory [6,27,[32][33][34][35][36][37][38] and density functional theory (DFT) calculation based on plane wave pseudo potential method [39][40][41]. The band-gap width, CB/VB of the catalysts series BiOX (X = F, Cl, Br, I) semiconductor were calculated by means of DFT method [42].…”

Atypical BiOCl/Bi2S3 hetero-structures exhibiting remarkable photo-catalyst response

“…Chang et al [38] coupled BiOCl with a narrow band gap material, NaBiO 3 . Moreover, BiOCl nanoparticles were dispersed uniformly on the both surfaces of graphene sheets to form a sandwich-like structure.…”

Solid-base loaded WO3 photocatalyst for decomposition of harmful organics under visible light irradiation

“…24,25 Photocatalyst of 0.4 g was put on a glass dish having bottom area of about 8 cm 2 . Then, the dish was set on the bottom of 500 cm 3 glass reactor.…”
