The construction of double type II heterostructure from CdS and Ni-MOF-74 with two structures and enhanced mechanism of photocatalytic water splitting

Synthesis of hierarchical Cd-Ni-MOF micro/nanostructures and derived Cd-Ni-MOF/CdS/NiS hybrid photocatalysts for efficient photocatalytic hydrogen evolution

“…Meanwhile, the typical intrinsic absorption edge of Cd-Ni-MOF-T is located at 400 nm. 27,49 Fig. 8b shows the converted plots based on the Kubelka–Munk function vs. photon energy, 50 from which the bandgap ( E g ) energy of CdS and Cd-Ni-MOF-T can be roughly estimated to be 1.99 and 2.41 eV, respectively.…”

“…[20][21][22][23] In particular, Ni-MOFs, as the substrate of CdS-based materials, enhance the separation of photoinduced carriers and significantly promote hydrogen production. [24][25][26][27] In addition, MOF-derived CdS/NiS materials have shown outstanding photocatalytic performance. 28 For instance, Su et al reported that the activity of NiS/CdS composites derived from Ni-MOFs, using terephthalic acid as a ligand, is higher than that of other ligands.…”

Synthesis of Hierarchical CdS/NiS Photocatalysts Using Ni−MOF‐74 as Template for Efficient Ethanol Conversion and Hydrogen Production under Visible Light

“…The synthesis of NiÀ MOF-74 is consistent with the methods reported in previous literature. [36] First, 880 mg of NiCl 2 • 6H 2 O, 240 mg of terephthalic acid, and 100 mg of polyvinylpyrrolidone were added to a 60 mL mixture of dimethylformamide (DMF), ethanol, and water in a volumetric ratio of 2 : 2 : 1. After stirring for 1 h, the above solution was poured into a Teflon-lined autoclave and was maintained at 150 °C for 10 h. Then Preparation of NiS: NiS were synthesized by a hydrothermal method.…”
