Synthesis of In₂S₃microspheres using a template-free and surfactant-less hydrothermal process and their visible light photocatalysis

Band gap-engineered ZnO and Ag/ZnO by ball-milling method and their photocatalytic and Fenton-like photocatalytic activities

“…The excitation wavelength was fixed to 320 nm to take the PL spectra. The •OH radical reacts with TA to produce 2-hydroxyterephthalic acid [46][47][48][49]. The product is luminescent, showing a broad photoluminescence (PL) signal at approximately 425 nm under the excitation of UV light.…”

“…The UV-visible absorption spectrum of the dye solution was measured using a UV-Vis spectrophotometer (Jasco V-530) with different light irradiation times. To detect the formation of active •OH radicals during light irradiation, the catalyst was dispersed in a terephthalic acid solution and irradiated with visible light [46][47][48][49]. Upon the irradiation of light for a specified time, the photoluminescence of the solution was measured at an excitation wavelength of 320 nm using a SCINCO FluoroMate FS-2.…”

Hollow Structured Metal Sulfides for Photocatalytic Hydrogen Generation

“…In 2 S 3 is n‐type semiconductor material for the photodegradation of organic pollutants and photocatalytic water splitting under visible light irradiation due to its desirable bandgap energy (2.0–2.4 eV) and suitable band edges (E CB =0.9 eV, E VB =1.3 eV). Additionally, it exhibits outstanding properties such as high photosensitivity and photoconductivity, good transparency, stable chemical and physical characteristics, and low toxicity . Under atmospheric pressure, In 2 S 3 may exist in three different phases: cubic structure α ‐In 2 S 3 , spinel structure β ‐In 2 S 3 , and layered structure γ ‐In 2 S 3 .…”

In2S3 nanomaterial as a broadband spectrum photocatalyst to display significant activity

“…In 2 S 3 exhibits three different structural forms: ␣-In 2 S 3 , ␤-In 2 S 3 , and ␥-In 2 S 3 . Among these crystalline structures, ␤-In 2 S 3 , the most stable structural form, has been extensively investigated as an excellent visible light-driven photocatalyst and sensitizer for wide band-gap semiconductor photocatalysts [25][26][27]. More importantly, due to the defect spinel structure of ␤-In 2 S 3 , it can allow the existence of intrinsic vacant sites.…”
