One pot milling route to fabricate step-scheme AgI/I-BiOAc photocatalyst: Energy band structure optimized by the formation of solid solution

Photocatalytic Activity of S-Scheme Heterostructure for Hydrogen Production and Organic Pollutant Removal: A Mini-Review

“…The photocatalytic experimental conditions use extreme values in terms of pollutant concentration (100 mg/L) and photocatalyst dosage (50 mg/15 mL). As mentioned before describing other similar reports [67,73], the phenol compounds are more resistant to photocatalytic decomposition. The S-scheme mechanism uses photogenerated holes in TiO 2 as recombination charges for the electrons from Bi 2 O 3 , resulting in more available photogenerated electrons in the TiO 2 conduction band for •O 2 − production.…”

“…An interesting study was done on an AgI nanoparticles (E G = 2.75 eV)/I-BiOAc nanosheets (E G = 2.35 eV) S-scheme heterostructure [ 73 ] obtained by a one-pot milling procedure. Using the same experimental conditions (500 W Vis light intensity, 20 mg/50 mL photocatalyst dosage), the degradation of four organic pollutants was evaluated.…”

A novel step-scheme BiVO4/Ag3VO4 photocatalyst for enhanced photocatalytic degradation activity under visible light irradiation

“…12, it can be observed that h + play an important role in the degradation of MB. Hence, we proposed the step-scheme mechanism [56,57]. When BiVO4 and Ag3VO4 are in close contact to form a heterojunction, the ein Ag3VO4 spontaneously move to BiVO4 through their interfaces, generating an internal electric field at the interface.…”

“…Fu et al [56] designed an ultrathin 2D/2D WO3/g-C3N4 step-scheme heterojunction with excellent photocatalytic activity for H2-production. Jia et al [57] prepared a high-efficiency step-scheme AgI/I-BiOAc photocatalyst, which showed 50 times higher catalytic activity than AgI. Mei et al [58] investigated the catalytic performance of a g-C3N4/Ag3VO4 heterostructure for the degradation of MB.…”

Microwave-assisted synthesis of an RGO/CdS/TiO2step-scheme with exposed TiO2{001} facets and enhanced visible photocatalytic activity

“…31 Construction of an Stype heterojunction usually requires two n-type semiconductor photocatalysts. At present, S-scheme heterojunction photocatalysts such as WO 3 /g-C 3 N 4 , 32 TiO 2 /W 18 O 49 , 33 AgI/I-BiOAc 34 have been reported. CdS is recognized as one of the most promising n-type photocatalytic materials due to its negative conduction band edge position and narrow band gap ($2.4 eV).…”
