Protecting TiS₃ Photoanodes for Water Splitting in Alkaline Media by TiO₂ Coatings.

ABSTRACT: Titanium trisulfide (TiS₃) nanoribbons, when coated with titanium dioxide (TiO₂), can be used for water splitting in the KOH electrolyte. TiO₂ shells can be prepared through thermal annealing to regulate the response of TiS₃/TiO₂ heterostructures by controlling the oxidation time and growth atmosphere. The thickness and structure of the TiO₂ layers significantly influence the photoelectrocatalytic properties of the TiS₃/TiO₂ photoanodes, with amorphous layers showing better performance than crystalline ones. The oxide layers should be thin enough to transfer photogenerated charge through the electrode-electrolyte interface while protecting TiS₃ from KOH corrosion. Finally, the performance of
