Abstract

We developed dye-sensitized photocatalytic systems (DSPs) by utilizing porphyrins as a photosensitizer (PS) or as a photosensitizer–catalyst (PS/CAT) upon their chemisorption onto platinum-doped titanium dioxide nanoparticles (Pt-TiO₂ NPs). The DSPs coated with Pt-Tc₃CP (PS/CAT entity) exhibited a record-high stability (25 500 TONs) and H₂ evolution activity (707 mmol g⁻¹ h⁻¹) compared to similar DSPs in the literature.
