In-situ deposition of metal Bi on BiOBr/CdS S‐scheme heterojunction for effective photocatalytic H2O2 evolution via a two channel pathway

Microdroplet assisted hollow ZnCdS@PDA nanocages’ synergistic confinement effect for promoting photocatalytic H2O2 production

“…6c). 21,[35][36][37][38][39][40][41] O 2 availability is considered to be crucial for H 2 O 2 generation but is largely restricted in the bulk solution phase due to its low solubility, slow diffusion coefficient and long-diffusion distance. 42 The photocatalytic H 2 O 2 production in bulk solution under the static and dynamic conditions was designed (Fig.…”

Synergistic redox reactions toward co‐production of H2O2 and value‐added chemicals: Dual‐functional photocatalysis to achieving sustainability

“…In addition, Fang et al prepared a BiOBr/CdS heterostructure via a solvothermal method (Figure 12E). 43 Notably, the heterojunction was applied to perform twochannel H 2 O 2 photoevolution with rate of 346.4 μmol g −1 h −1 , which is principally identical to that previously mentioned in the g-C 3 N 4 section. The DFT computational and experimental results corroborated that the composite was of S-scheme nature, as illustrated in Figure 12F.…”

Preparation of Heterojunction Catalysts for Photocatalysis byin‐situSynthesis: What We Should Do Next?

“…Bi/BiOBr-CdS [101] in-situ hydrothermal synthesis with Bi(NO 3 ) [106] in-situ sulfurization of MIL-125@ZIF- phase would oxidize benzyl alcohol to benzaldehyde during the photocatalytic process (Figure 25e). In this process, H 2 O was converted to O 2 at the Co-doped ZnIn 2 S 4 via a four-electron oxidation reaction, and then O 2 was reduced and protonated on the surface of Co 9 S 8 to form H 2 O 2 (Figure 25f).…”
