Influence of calcination on the structural properties of earth abundant Cu2ZnSnS4

A Salt‐Resistant and Antibacterial Cu2ZnSnS4‐Based Hydrogel for High Efficient Photothermal Distillation in Seawater Desalination and Sewage Purification

“… [42] In addition, Raman analysis was performed on the synthesized samples. The strong peak at 331 cm −1 and the acromion peak at 287 cm −1 can be attributed to the main and second A mode of kesterite, which confirm the successful synthesis of the CZTS (Figure S5) [43] …”

“…The strong peak at 331 cm À 1 and the acromion peak at 287 cm À 1 can be attributed to the main and second A mode of kesterite, which confirm the successful synthesis of the CZTS (Figure S5). [43] The valence states of elements in CZTS nanoparticles were studied by X-ray photoelectron spectroscopy (XPS) analysis (Figure 3d-g and Figure S6). It can be seen that there are two peaks of 931.68 eV and 951.58 eV with a splitting degree of 19.9 eV in the Cu 2p spectrum, which is same as the standard separation degree (19.9 eV) of Cu I .…”
