Abstract

En 中文

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. Dye-sensitized photocatalytic systems (DSPs) for H2 evolution were developed, by utilizing porphyrins as photosensitizer-catalyst (PS/CAT) entities onto platinum-doped titanium dioxide nanoparticles (Pt-TiO2 NPs).
