Mechanism insights into the facet-dependent photocatalytic degradation of perfluorooctanoic acid on BiOCl nanosheets

Photo-chemical/catalytic oxidative/reductive decomposition of per- and poly-fluoroalkyl substances (PFAS), decomposition mechanisms and effects of key factors: a review

“…In addition, in search of more efficient alternatives, researchers demonstrated the viability of bismuth-based photocatalysts such as BiOCl, 131,132 BiOI, 133 BiFeO 3 , 134 and BiPO 4 135,136 for the decomposition of PFOA. Compared with conventional photocatalysts ( e.g.…”

Solar photo-oxidation of recalcitrant industrial wastewater: a review

“…4), ultraviolet light range λ < 400 nm is used for illumination, and titanium dioxide semiconductor acts as a catalyst. Titanium dioxide stands out among other semiconductors because of its large surface area, regular shape and size of particles, high stability, and ability to use sunlight as a light source (Fatima and Kim 2021;Mohanta and Ahmaruzzaman 2021;Wu et al 2021b). Photons with energies greater than the bandgap energy excite valence band electrons in the photocatalysis oxidation process, boosting interactions with organic contaminants (Mohanta and Ahmaruzzaman 2021;Huang et al 2021).…”

Synthesis and characterization of an ultra-thin BiOCl/MXene heterostructure for the detection of NO2 at room temperature with enhanced moisture resistance

“…12 BiOCl crystals are layered structures formed by [X-Bi-O-Bi-X] sheets stacked together along the c-axis by van der Waals interactions. 13,14 The interaction of strong covalent bonds and weak van der Waals forces makes BiOCl highly attractive in many applications, such as photocatalytic treatment of wastewater, 15 indoor gas purication, 16 and water purication. 17 However, there are few reports on bismuth oxychloride in gas sensing to date.…”
