“…The CZTS films synthesized on Mo and FTO display other kesterite CZTS peaks at ~ 283 cm -1 and 473 cm -1 , which are in agreement with the previous report [30,40]. However, the difference in peaks intensity is well observed and could be related to different reasons.…”

“…However, the evidence for Sn 2+ ( 485 eV) was not observed in the spectra. The binding energies of Sn 3d in CTS were shifted to lower energy area along with the decreased content of Cu because of the enhanced Cu/Sn disordering [47]. The S region in Fig.…”

Broad absorption spectra with efficient generation and separation of available charge carriers are indispensable requirements for promising semiconductor-based photocatalysts to achieve the ultimate goal of solar-to-fuel conversion. Here, Cu 3−x SnS 4 (x = 0-0.8) with copper vacancies have been prepared and fabricated via solvothermal process. The obtained copper vacancy materials have extended light absorption from ultraviolet to near-infrared-II region for its significant plasmonic effects. Time-resolved photoluminescence shows that the vacancies can simultaneously optimize charge carrier dynamics to boost the generation of long-lived active electrons for photocatalytic reduction. Density functional theory calculations and electrochemical characterizations further revealed that copper vacancies in Cu 3−x SnS 4 tend to enhance hydrogen's adsorption energy with an obvious decrease in its H 2 evolution reaction (HER) overpotential. Furthermore, without any loadings, the H 2 production rate was measured to be 9.5 mmol•h −1 •g −1 . The apparent quantum yield was measured to be 27% for wavelength λ > 380 nm. The solar energy conversion efficiency was measured to be 6.5% under visible-near infrared (vis-NIR) (λ > 420 nm).
