The new method of ZnIn₂S₄ synthesis on the titania nanotubes substrate with enhanced stability and photoelectrochemical performance.

ABSTRACT: In this work, ZnIn₂S₄ layers were obtained on fluorine doped tin oxide (FTO) glass and TiO₂ nanotubes (TiO₂NT) using a hydrothermal process as photoanodes for photoelectrochemical (PEC) water splitting. Then, samples were annealed and the effect of the annealing temperature was investigated. Optimization of the deposition process and annealing of ZnIn₂S₄ layers made it possible to obtain an FTO-based material generating a photocurrent of 1.2 mA cm^-2 at 1.62 V vs. RHE in a neutral medium. In contrast, the highest photocurrent in the neutral electrolyte obtained for the TiO₂NT-based photoanode reached 0.5 mA cm^-2 at 1.62 V vs. RHE. In addition, the use of a strongly acidic electrolyte allowed t
