Modulating formation rates of active species population by optimizing electron transport channels for boosting the photocatalytic activity of a Bi₂S₃/BiO_1−xCl heterojunction

Abstract

Sodium persulfate (PS) is a promising oxidant in advanced oxidation technologies (AOPs) while the uncontrollable decomposition limits application. Herein, Bi2S3/BiO1-xCl heterojunction with appropriate oxygen vacancies (OVs) was synthesized via microwave-assisting,...

Enhancing the separation efficiency of photo-induced carriers in a Bi2S3/BiOCl heterostructure by cooperative influence of oxygen vacancies and the interfacial electric field

“…It is well-documented that reasonable OVs will promote the separation of photogenerated carriers due to them serving as electron traps, which will eventually improve the photocatalytic activity. 26 Thereby, we boldly predicted that the as-synthesized catalysts will exhibit good performance.…”

“…In addition, the IEF yield from the heterostructure interface will drive the photo-induced electron-hole pairs to transfer to the opposite direction, thus tremendously improving the separation efficiency of the photogenerated carriers. 25,26 However, few reports have focused on how to amend the photocatalytic property by the coupling of appropriate OVs and the IEF.…”
