“… 19 For instance, tin indium sulfide (SnIn 4 S 8 ) as a novel ternary chalcogenide semiconductor has exhibited potential application in photocatalytic reduction of heavy metal ion. But single SnIn 4 S 8 semiconductor owns a small specific surface area and fast electron–hole recombination, 20 which result in the decrease of photocatalytic activity. Graphene with one-atom-thick layer and two-dimensional nano scale of sp 2 -bonded carbon structure, taking advantage of higher surface activity and specific surface area per unit volume, has been applied to combine with semiconductor photocatalysts such as TiO 2 , Fe 3 O 4 , Gd(OH) 3 , CdS and CuInS 2 .…”

“…The physical and chemical ability of nanomaterials is mainly determined by their size, structure, and morphology. SnIn 4 S 8 nanosheets have a large specific surface area, which may facilitate visible-light absorption [43] and reduce film resistance due to the fast charge transfer between the nanosheet and the electrolyte [44]. In addition, SnIn 4 S 8 nanosheets have a relatively negative conduction band, which is beneficial to providing photocathodic protection for metals with a negative self-corrosion potential.…”

TiO2 is an attractive semiconductor suitable for photocathodic protection, but its weak absorption of visible light and low quantum yield limit its usage. Here, a new heterostructured SnIn4S8 nanosheet/TiO2 nanotube photoanode was prepared and its photocathodic protection performance was analyzed. SnIn4S8 nanosheets were uniformly deposited on the surface of the TiO2 nanotube via a solvothermal treatment. The SnIn4S8/TiO2 composite exhibited better photocathodic protection performance compared with pure TiO2 nanotubes, owing to its good visible-light response and photogenerated carrier separation efficiency. Moreover, the composite exhibited a maximum photocurrent density of 100 μA cm−2 for a 6 h solvothermal reaction under visible light irradiation. The negative shift of the photoinduced potential of Q235 carbon steel connected to the composite could reach 0.45 V versus SCE. Therefore, the SnIn4S8/TiO2 composite can offer efficient photocathodic protection for Q235 carbon steel against corrosion in 3.5 wt% NaCl solution. This work provides a new approach for the development of high-efficient photoanode materials for the photocathodic protection of metals.

“…Binary chalcogenides are not resistant to photocorrosion by photogenerated holes and show low chemical stability in photocatalytic processes [ 19 ]. In contrast, ternary chalcogenides demonstrate high stability, narrow band gap, and strong absorption of visible light, which are highly desirable properties for photocatalytic processes [ 20 ]. Among these ternary chalcogenides, AgInS 2 , CdIn 2 S 4 , CaIn 2 S 4 , SnIn 4 S 8 , and ZnIn 2 S 4 have been reported to be efficient photocatalysts for visible-light-driven H 2 evolution or degradation of pollutants [ 21 , 22 , 23 , 24 , 25 ].…”

Photocatalytic Degradation of Ethiofencarb by a Visible Light-Driven SnIn4S8 Photocatalyst

This work reports the preparation and detailed characterization of stannum indium sulfide (SnIn4S8) semiconductor photocatalyst for degradation of ethiofencarb (toxic insecticide) under visible-light irradiation. The as-prepared SnIn4S8 showed catalytic efficiency of 98% in 24 h under optimal operating conditions (pH = 3, catalyst dosage of 0.5 g L−1). The photodegradation reaction followed pseudo-first-order kinetics. The major intermediates have been identified using gas chromatography/mass spectrometry. •O2− and •OH radicals appeared to be the primary active species in the degradation process as revealed by scavenger and electronic spin resonance studies, while photogenerated holes had a secondary role in this process. A plausible mechanism involving two routes was proposed for ethiofencarb degradation by SnIn4S8 after identifying the major intermediate species: oxidative cleavage of the CH2-S and the amide bonds of the carbamate moiety. Lastly, SnIn4S8 was found to be efficient, stable, and reusable in treating real water samples in three successive photodegradation experiments. This study demonstrates the prospect of SnIn4S8 photocatalysis in treatment of natural and contaminated water from extremely toxic organic carbamates as ethiofencarb.
