Synthesis and formation mechanism of CuInS₂ nanocrystals with a tunable phase

Abstract

The photocatalytic properties of chalcopyrite and wurtzite CIS in visible-light-driven degradation of organic dye were also compared.

The phase transformation of CuInS2 from chalcopyrite to wurtzite

“…Figure 1b shows the XRD pattern of the products synthesized at pH of 10.3. The peak position and relative peak intensities can match well with the powder diffraction data reported for wurtzite CuInS 2 [9,[13][14][15]. The diffraction patterns were simulated using the lattice parameters previously reported for wurtzite CuInS 2 (simulated by using the software Diamond 3.2, with the space group of P63mc and lattice parameters a = b = 3.897 Å, c = 6.441 Å [9]), and it matched well with our experimental XRD diffraction pattern.…”

Photocatalytic activity of CuInS2 nanoparticles synthesized via a simple and rapid microwave heating process

“…Copper indium sulfide (CuInS 2 ) is an interesting ternary metal sulfide that has a wide range of potential applications including photocatalysis [14][15][16][17][18], in photodetectors [19], bioimaging [20,21] and in solar cells [22,23]. Its conduction band is constructed from 5s orbital of In and its valence band consists of 3p orbitals of S [12]; thereby, a narrower band gap energy (1.53 eV for the bulk) can be achieved.…”

“…Its conduction band is constructed from 5s orbital of In and its valence band consists of 3p orbitals of S [12]; thereby, a narrower band gap energy (1.53 eV for the bulk) can be achieved. In the photocatalysis, it has been explored as a photocatalyst for H 2 evolution [14,15,24,25], organic pollutant degradation [16,26,27], and nitrate ion reduction [17,18]. Hydro/solvothermal methods have been used to synthesize CuInS 2 nanoparticles [28][29][30][31][32].…”

Effect of sulfonating agent and ligand chemistry on structural and optical properties of CuSbS2particles prepared by heat-up method

“…Pursuit after new suitable, non-toxic, and abundant semiconductor materials 1-4 for different applications is a continuous challenge in materials science. In this quest ternary and quaternary semiconductors like CuSbS2, CuInS2 5,6 , CuInSe2 7 , CuInGaS2 8 and Cu2ZnSnS4 9 have gained increasing interest. Among these CuSbS2 is particularly interesting, but less explored material.…”
