Rapid Surface Reconstruction of In<sub>2</sub>S<sub>3</sub> Photoanode via Flame Treatment for Enhanced Photoelectrochemical Performance (Adv. Mater. 26/2025)
Flame Treatment A rapid and scalable high-temperature flame technique is developed to enable surface reconstruction of sulfide semiconductor photoelectrode for enhanced photoelectrochemical(PEC) performances. In article number 2403164, Sung Sik Shin, Xiaolin Zheng, Sun Cho, and their team demonstrate rapid surface reconstruction of Indium sulfide (In2S3) photoanode using the flame process. The flame process transforms the In2S3 surface into a 5 nm-thin In2O3 layer and generates bulk sulfur vacancies simultaneously, leading to a remarkable PEC water oxidation photocurrent density of 8.5 mA cm−2 and iodide oxidation photocurrent density of 7.3 mA cm−2.
