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

“…18 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. 19 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 . 20−22 Even so, the photocatalytic ability of BiOBr is restricted to its limited separation of photogenerated charges and response of visible light.…”

“…BiOBr (band gap of ∼2.8 eV) has attracted a number of interests owing to its outstanding electrical property and good photocatalytic performance, leading to potential application in photocatalytics, electrocatalytics, supercapacitors, Li-ion batteries, and solar cells. − Particularly, BiOBr exhibits a unique layered structure, which is composed of tetragonal [Bi 2 O 2 ] layers and double slabs of Br atoms .

Phosphorus-modified two-dimensional graphdiyne (CnH2n−2)/ZnCdS forms S-scheme heterojunctions for photocatalytic hydrogen production

“…4 Therefore, it is of great significance to produce highly active and stable photocatalytic hydrogen evolution catalysts to replace noble metal materials for hydrogen production from water to solve the energy problems. [5][6][7] In recent years, the excellent stability and durability of carbon-based materials have gradually replaced the application of precious metals in the catalytic field, such as carbon nanotubes, carbonitride, [8][9][10] graphene, [11][12][13] C 60 , 14,15 and biological carbon. 16,17 Since the first synthesis of a new carbon material, graphdiyne (GDY), by Yuliang's group in 2010, 18,19 the scientific community has further explored it.…”
