Investigations on the structural, optical and visible light photocatalytic activity of Cu3SnS4 prepared by mechanical alloying

Controllability study of copper‐tin‐sulphide (Cu3SnS4) material based on the ratio adjustment of Cu to Sn elements

“…Mechanical alloying is a complex physical and chemical process in which the powder undergoes repeated deformation, cold welding, and crushing by high‐energy ball milling to achieve atomic‐level alloying between elements. To obtain the required Cu 3 SnS 4 material simply and effectively, Maheskumar, Gururajan [40] used the method of mechanical ball milling to mix Cu powder (99.90%), Sn powder (99.85%), and S powder (99.90%) according to the atomic ratio of 3:1:4. The ratio of metal elements in the ternary phase was controlled by adjusting the ball milling time, and the time range was controlled between 20 and 60 h. The XRD results of the samples are shown in Figure 2.…”

“…The preparation methods of Cu 3 SnS 4 mainly include the physical method and chemical method. Physical methods include the vacuum evaporation method [37][38][39], mechanical alloy method [40,41], magnetron sputtering method [42][43][44][45] etc. To investigate the effect of Ag doping on the thermoelectric properties of CTS, Lohani, Nautiyal [5] synthesize various Cu 2 Ag (x) Sn (1−x) S 3 (0.05 ≤ x ≤ 0.25) samples by mechanical alloying followed by spark plasma sintering, and their structural and transport properties were systematically investigated.…”

Iron alloying improved electrocatalytic activity of Cu2Cu1−xFexSnS4 counter electrodes in dye-sensitized solar cells

“…Among them, due to abundant raw materials, easy preparation process, good conductivity and electrocatalytic activity, copper sul des have potential applications and are expected to be an alternative for Pt-free CEs. Cu 3 SnS 4 (CTS) is a P-type semiconductor with an optical bandgap of 1.2 to 1.7 eV [30][31][32][33][34], and has a high light absorption coe cient in a wide waveband ranging from UV to near-infrared [35,36]. CTS has been studied in elds including photocatalytic degradation [37][38][39][40], photocatalytic hydrogen evolution reaction [40][41][42], gas sensor [43], thermoelectric conversion [44].…”
