Construction of CdS/MoS2 heterojunction from core–shell MoS2@Cd-MOF for efficient photocatalytic hydrogen evolution

Author affiliations

Abstract

A new synthetic method was used to develop a CdS/MoS2 heterojunction. Cd-MOF was coated onto the surface of MoS2 flowers to construct a core–shell MoS2@Cd-MOF. Thioacetamide was used as a sulfur source to sulfurize the MoS2@Cd-MOF to form a CdS/MoS2 heterojunction. Since the Cd2+ ions were highly ordered and separated by the organic ligands of the Cd-MOF shell, the as-synthesized CdS/MoS2 heterojunction possessed a large surface area and intimate contact at the heterogeneous interface with a uniform loading of CdS nanoparticles on the MoS2 flowers. Consequently, the CdS/MoS2 heterojunction exhibited a significantly enhanced photocatalytic H2 evolution rate of average 5587 μmol h−1 g−1 under UV-visible light irradiation.
