Abstract Surface reconstruction, reorganizing the surface atoms or structure, is a promising strategy to manipulate materials' electrical, electrochemical, and catalytic properties. Herein, rapid reconstruction of indium sulfide (In 2 S 3 ) demonstrated via high‐temperature flame treatment improve its charge collection The process selectively transforms In into diffusionless O layer with high crystallinity. Additionally, it controllably generates bulk sulfur vacancies within few seconds, leading surface‐reconstructed (sr‐In ). When using those sr‐In as photoanode for photoelectrochemical water splitting devices, these dual functions /bulk reduce recombination in region, thus improving photocurrent density stability. With optimized demonstrates significant 8.5 mA cm −2 at 1.23 V versus reversible hydrogen electrode (RHE), marking 2.5‐fold increase compared pristine (3.5 More importantly, exhibits an impressive 7.3 0.6 RHE iodide oxidation reaction. A practical scalable also showcased treatment. This work provides new insights engineering sulfide‐based semiconductors, making breakthrough developing efficient solar‐fuel energy devices.

Photoelectrochemical (PEC) water splitting for hydrogen production using the CdTe photocathode has attracted much interest due to its excellent sunlight absorption property and energy band structure. This work presents a study of engineered interfacial energetics photocathodes by deposition CdS, TiO2, Ni layers. A heterostructure CdTe/CdS/TiO2/Ni was fabricated depositing 100-nm n-type CdS layer on p-type surface, with 50 nm TiO2 as protective 10 co-catalyst. The exhibits high photocurrent density (Jph) 8.16 mA/cm2 at 0 V versus reversible electrode (VRHE) positive-shifted onset potential (Eonset) 0.70 VRHE PEC evolution under 100 mW/cm2 AM1.5G illumination. We further demonstrate that CdTe/CdS p-n junction promotes separation photogenerated carriers, protects from corrosion, catalyst improves charge transfer across electrode/electrolyte interface. provides new insights designing noble metal-free toward solar development.

Understanding metal–semiconductor interfaces is critical to the advancement of photocatalysis and sub-bandgap solar energy harvesting where electrons in metal can be excited by photons extracted into semiconductor. In this work, we compare electron extraction efficiency across Au/TiO2 titanium oxynitride (TiON)/TiO2–x interfaces, latter case spontaneously forming oxide layer (TiO2–x) creates a contact. Time-resolved pump–probe spectroscopy used study recombination rates both cases. Unlike nanosecond lifetimes Au/TiO2, find bottleneck relaxation TiON system, which explain using trap-mediated model. Using model, investigate tunability dynamics with oxygen content parent film. The optimized film (TiO0.5N0.5) exhibits highest carrier (NFC ≈ 2.8 × 1019 m–3), slowest trapping, an appreciable hot population reaching surface (NHE 1.6 1018 m–3). Our results demonstrate productive role play enhancing prolonging lifetimes, providing interface only native oxynitride.
