In situ grown CdS on 2D Cd-based porphyrin MOFs enhances the significant separation and transfer of charge carriers with an appropriate heterojunction during photocatalytic hydrogen evolution

Abstract

This work provided a novel and reliable idea for preparing the integrated metal-sulfides/2D-MOFs via in situ grown strategy to realize the significant separation and transfer of charge carriers.

Photocatalytic hydrogen evolution over Pt–Pd dual atom sites anchored on TiO2 nanosheets

“…5,6 Compared with industrial hydrogen production and electrochemical hydrogen production, photocatalytic hydrogen evolution is undoubtedly the most sustainable and involves least energy consumption. 7 At present, among various semiconductors (such as CdS, [8][9][10] g-C 3 N 4 , [11][12][13] and TiO 2 (ref. 14 and 15)) as photocatalysts, titanium dioxide (TiO 2 ) is considered to be the most suitable photocatalyst for hydrogen production via water splitting due to its low cost, nontoxicity, high catalytic selectivity, and longterm photostability.…”

Porphyrin-Based Metal-Organic Framework Materials: Design, Construction, and Application in the Field of Photocatalysis

“…Therefore, porphyrin-based MOFs obtained by integrating porphyrins with metal nodes become multifunctional carriers with excellent photocatalytic performance and desired functionality [ 39 , 40 ]. Thus, porphyrin-based MOFs have received significant attention due to their tremendous potential in various fields, such as photocatalysis [ 41 , 42 , 43 ], biomedicine [ 44 , 45 , 46 , 47 ], electrochemistry [ 48 , 49 , 50 , 51 ], and molecular adsorption [ 52 ]. Especially in the design of new photocatalytic materials, the photocatalytic activity of porphyrin-based MOFs can be regulated by the design of porphyrin molecule structure, and can also be optimized by the co-structure design of mixed ligands in MOF and the co-assembly doping design with other materials.…”
