Synergistic Effects of Carbon Dots and Palladium Nanoparticles Enhance the Sonocatalytic Performance for Rhodamine B Degradation in the Absence of Light

“…Whereas in the presence of the nanohybrid catalyst, the LC−MS spectra obtained during the course (time intervals 0−5 min) of the reaction showed gradual fragmentation of peaks and led to small molecules of 74 and 81 Da at the end of the reaction. The possible degradation products are provided in Figure S12 of the Supporting Information, and the observed fragmentation molecules match well with the previous reports. − …”

Microwave-assisted synthesis of a Z-scheme heterojunction Ag/AgBr@BiOBr/Bi2O3 photocatalyst for efficient organic pollutant degradation under visible light

“…1a). 8,23,24 XRD peaks also confirmed the presence of AgBr at 26.7, 31.0, 44.3, 55.1, and 73.3°2θ corresponding to the (111), ( 200), ( 220), (222), and (420) planes, respectively. These peaks were indexed to the JCPDS #06-0438 profile, which belongs to the cubic structure of AgBr (Fig.…”

S-Scheme In2O3 Nanoparticle/BiOBr Nanoplate Heterojunctions for Improved Photocatalytic Dye Degradation and Cr(VI) Reduction

“…In this lamellar structure, the internal electric fields will be formed between [Bi 2 O 2 ] 2+ positive layers and Br – negative layers, which is expected to promote the separation of photogenerated charges . The abovementioned outstanding properties and structure of BiOBr give rise to the favorable visible-light photocatalytic degradation performance, reduction of heavy metal ions, and production of H 2 . − Even so, the photocatalytic ability of BiOBr is restricted to its limited separation of photogenerated charges and response of visible light . Accordingly, many modifications have been focused on the improvement of the photocatalytic performance of BiOBr, which is mostly via construction of Type-II and p–n type heterojunctions. − The abovementioned two traditional heterojunctions accelerate the separation of photogenerated electrons, and holes suffer from the weakening of photocatalytic redox ability, resulting in the limited improvement of photocatalytic performance. , In contrast, the development of step-scheme (S-scheme) heterojunctions can not only promote the separation of photoinduced electrons and holes but also keep their strong photocatalytic redox capacity.…”
