Abstract Transition metal sulfides (TMS) exhibit significant promise as non‐noble‐metal electrocatalysts for the oxygen evolution reaction (OER) in alkaline environments, notwithstanding their susceptibility to long‐term instability due gradual leaching of surface‐reconstructed sulfate ions (SO 4 2− ). In this study, a ion‐assisted strategy is proposed stabilize SO FeNiS 2 . The findings reveal that experiences considerable loss KOH infinite concentration gradient on surface. Conversely, K /KOH, mitigates rapid and preserves predominant , thereby enhancing stability both accelerated degradation (5000 cycles) (≥120 h) tests, with ≈95% current density retained. Furthermore, optimal proves be crucial, supported by experimental theoretical results. This approach offers insights into bolstering OER TMS similar compounds, advancing prospects widespread application electrocatalytic water splitting.

In this work, suitable band gap width, strong photo-response to visible light, and a high photogenerated carrier density offered by an important member of layered sulfides, SnS2, were kept in view for designing producing highly effective photocatalyst CO2 reduction. Hence, SnS2/CeO2 heterojunction composite photocatalysts triumphally fabricated facile situ hydrothermal synthesis method, combining advantages the built-in electric field oxygen vacancies two materials. Various characterization techniques exploited scrutinize photocatalyst's structure confirm that transport efficiency photocatalytic performance are enhanced synergistic impact presence vacancies. Owing successful loading zero-dimensional CeO2 nanoparticles onto two-dimensional SnS2 nanosheets, 2D/0D improves range composites provides faster electron transfer rates. The material maintained hydrophobic characteristic single while inhibiting hydrophilic property CeO2. As result, CO CH4 yields prepared binary Z-type 24.6 4.4 folds higher than those respectively. This innovative study will contribute exploration SnS2-based materials provide new feasible direction light energy-driven
