“…The peaks at 159.24 eV and 164.41 eV were assigned to Bi 4f 7/2 and Bi 4f 5/2 in Fig.1c[26,27]. The peak at 530.56 eV (Fig.1d) was attributed to O 2ion in Bi-O[28][29][30]. The peaks of Bi and O had no change after PNIPAM modification, indicating that the PNI-PAM coating did not influence the existence of Bi 2 O 3 .…”

“…After exciting, the holes react with water or adsorb OH − and can directly accept electrons of organic matter. At the same time, the exciting electrons react with dissolved dioxygen to produce hydroxyl and superoxide radicals 4,13 . The wide bandgap of TiO 2 photocatalyst (3–3.2 eV) is prone to be active by visible light radiation.…”

“…Several strategies have been developed to solve the above‐mentioned problems, such as metal and non‐metal doping (surface engineering), 14,15,17 dye sensitization, 18 and coupling with the narrow bandgap semiconductors 19 . In addition, coating TiO 2 onto a media can increase its surface area to enhance the adsorption of the visible light irradiation 13 . Various studies have used some metals as dopants for TiO 2 such as Co, Cu, and Fe 5,6,20 .…”

“…No que tange à análise cinética dos dados obtidos, o modelo cinético simplificado de Langmuir-Hinshelwood (L-H) (Equação 16) é frequentemente usado para descrever a cinética de reações fotocatalíticas (Moraes et al, 2019). Ademais, vê-se que o óxido de bismuto puro (Tcal = 600 °C) apresentou a menor capacidade de degradação da molécula de 4-clorofenol sob radiação solar entre os materiais testados, provavelmente devido à sua alta taxa de recombinação das cargas fotogeradas, concordando com dados existentes na literatura relacionada às propriedades fotocatalíticas desse material (Benyamina et al, 2019;Medina et al, 2018;Wang et al, 2015).…”

“…A literatura reporta que, de maneira isolada, o óxido de bismuto apresenta fotoatividade inferior ao óxido de zinco, devido a uma maior taxa de recombinação entre as cargas fotogeradas nesse semicondutor (Benyamina et al, 2019;Medina et al, 2018;Wang et al, 2015). Dessa forma, a razão ideal entre ZnO e Bi2O3 deve favorecer o efeito das heterojunções na atividade fotocatalítica do material sem que o aumento na porcentagem de óxido de bismuto influencie negativamente a atividade do compósito.…”
