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.
采用一种新的合成方法制备了 CdS/MoS2 异质结。Cd-MOF 被包覆在 MoS2 花的表面上，构建了核壳结构的 MoS2@Cd-MOF。硫代乙酰胺被用作硫源，对 MoS2@Cd-MOF 进行硫化，形成 CdS/MoS2 异质结。由于 Cd2+ 离子被 Cd-MOF 壳的有机配体高度有序地隔开，因此所合成的 CdS/MoS2 异质结具有较大的表面积和在异质界面处的紧密接触，CdS 纳米粒子均匀地负载在 MoS2 花上。因此，CdS/MoS2 异质结在紫外可见光照射下表现出显著增强的平均 5587 μmol h-1 g-1 的光催化 H2 产生速率。
