Abstract

Photocatalytic hydrogen (H₂) evolution from organic substrates is an appealing process since H₂ and high-value chemicals can be simultaneously produced by harnessing solar radiation through the utilization of semiconductor photocatalysts. Herein, we report the preparation of CdS/NH₂-UiO-66(Zr) nanocomposites, in which CdS quantum dots (QDs) are firmly immobilized on NH₂-UiO-66(Zr) through a robust covalent assembly strategy. The resulting CdS/NH₂-UiO-66(Zr) nanocomposites demonstrate remarkable performance in the coproduction of hydrobenzoin (HB) and H₂ from benzyl alcohol under visible-light irradiation, owing to the strong interfacial interaction. The significantly superior activity exhibited over the CdS/NH₂-UiO-66(Zr) nanocomposites, when contrasted with that over a simple grinding of CdS and NH₂-UiO-66(Zr), strikingly emphasizes the pivotal significance of rational interface engineering within photocatalytic systems. This work presents a green and sustainable approach for the synthesis of hydrobenzoins and paves the way for further exploration and optimization of semiconductor QDs/metal-organic frameworks nanocomposites.
