Copper indium sulfide quantum dots in photocatalysis

Exploration of the g-C3N4 Heterostructure with Ag–In Sulfide Quantum Dots for Enhanced Photocatalytic Activity

“…21−23 Semiconducting metal sulfides, especially I−III−VI polysulfides, have many advantages, such as strong visible light absorption, narrow band gap, excellent conductivity, chemical stability, and light corrosion resistance. 24,25 Indium sulfide (In 2 S 3 ) is an n-type semiconductor with a band gap energy of 2.0−2.3 eV, high photosensitivity, and low toxicity, and it has been studied in a heterostructure with other semiconductors, including GCN, in a few reports. 26−29 The photochemical properties of indium sulfide can be enhanced by the introduction of silver, obtaining I−III−VI sulfides with a range of stoichiometry, from doping levels to AgIn 5 S 8 and AgInS 2 .…”

After all, in view of the shortcomings of GCN, it is of practical significance to build a composite system of AIS QDs and GCN and optimize its optoelectronic properties by taking advantage of the unique properties of QDs.…”

“…Tetracycline (TC) is the most widely used low-cost broad-spectrum antibiotic with high antibacterial activity. It has multiple effects, such as growth promotion, tumour treatment and promoting bone absorption [7] . It has been widely detected in surface, groundwater, and drinking water.…”

Recyclable Copper Indium Sulfide Quantum Dots for Photocatalytic Homocoupling of Arenediazonium Tetrafluoroborates

“…55 However, as far as we know, there are few reports on the application of CuInS 2 QDs as a photocatalyst in organic synthesis. 56 In 2020, Weiss' group synthesized CuInS 2 /ZnS core−shell QDs and applied them as photocatalysts for photocatalytic reduction and deprotection of arylsulfonyl-protected phenol. 57 In 2022, Liu et al successfully prepared a three-dimensional flexible self-supporting material composed of CuInS 2 QDs and GO for efficient photocatalytic synthesis of xylonic acid from xylose.…”
