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-TiO<subscript>2</subscript> NPs). The DSPs coated with Pt-Tc<subscript>3</subscript>CP (PS/CAT entity) exhibited a record-high stability (25 500 TONs) and H<subscript>2</subscript> evolution activity (707 mmol g<superscript>−1</superscript> h<superscript>−1</superscript>) compared to similar DSPs in the literature.
