Amphiphilic, phosphonic acid-capped cadmium selenide quantum dots sensitize a thiomolybdate catalyst for hydrogen production

Combining a molecular thiomolybdate cluster, [Mo 3 S 13 ] 2− , with cadmium selenide quantum dots capped with tetraethyleneglycol monomethyl ether phosphonate (TEGPA) ligands results in a highly active photocatalytic system for the production of hydrogen under visible light irradiation. The system r...

Description
Summary:Combining a molecular thiomolybdate cluster, [Mo 3 S 13 ] 2− , with cadmium selenide quantum dots capped with tetraethyleneglycol monomethyl ether phosphonate (TEGPA) ligands results in a highly active photocatalytic system for the production of hydrogen under visible light irradiation. The system reaches turnover numbers exceeding 30 000 and remains active for ∼200 h. Combining a molecular thiomolybdate cluster, [Mo 3 S 13 ] 2− , with cadmium selenide quantum dots capped with amphiphilic ligands results in a highly active photocatalytic system for the production of hydrogen under visible light irradiation.
