Enhanced the photoelectrocatalytic performance of TiO2 nanotube arrays by the synergistic sensitization of Ag–AgBr nanospheres

Importance of ZnTiO3 Phase in ZnTi-Mixed Metal Oxide Photocatalysts Derived from Layered Double Hydroxide

“…Moreover, the reactive species controlling the oxidation of phenol was analyzed by trapping hydroxyl radicals (•OH), holes (h + ), and reactive oxygen species (•O 2 – ) with radical trapping agents, such as isopropyl alcohol (IPA, OH radical trappings), EDTA-2Na (hole trapping), and benzoquinone (BQ, superoxide radical trapping), during photocatalytic reactions . The radical scavenger tests were conducted under conditions that are similar to those of the photocatalytic test; however, 0.1 mM of scavengers were added before the reaction.…”

Synthesis and improved photoelectrochemical performances of oxygen-deficient TiO2/black-BaTiO3/CdS multiple-heterojunction nanoarrays

“…Under the irradiation of visible light, a large number of electrons are excited and gathered on the surface of the electrode, and the electron transfer is limited, and some electrons recombine with the hole, resulting in the reduction of the photocurrent. 50 Normally, the reduction temperature during the blackening process can greatly influence the concentration of oxygen vacancy in semiconducting oxides and then affect their band structures and photoelectric performances, as reported previously. 41 In this study, the effect of the Al-reduction temperature on the PEC performance of TiO 2 /B-BTO photoelectrode was also investigated.…”

Photocatalysis for Heavy Metal Treatment: A Review

“…Among heavy metal ions, the treatment of Cr(VI) ions is the most studied. Some works have been published on the photocatalytic reduction of Cr(VI) using TiO 2 -, ZnO-, CdS-, and ZnS-based catalysts [16,[50][51][52][53][54][55][56][57][58][59][60][61][62]65].…”
