Acid–base resistant ligand-modified molybdenum–sulfur clusters with enhanced photocatalytic activity towards hydrogen evolution

Abstract

The first trimeric [MoIV3S7] cluster of MoS-MBTZ containing both S and N coordination sites, obtained by ligand-modification engineering, displays high acid–base stability and excellent photocatalytic activity towards H2 evolution.

Triptycene-Based Polymer-Incorporated CdxZn1–xS Nanorod with Enhanced Interfacial Charge Transfer for Stable Photocatalytic Hydrogen Production in Seawater

“…To investigate the band structure of semiconductors, the flat band potentials ( V fb ) of Cd 0.6 Zn 0.4 S and TCP were measured using the Mott–Schottky (M–S) experiment (Figure c) . As seen from the positive slope of M–S plots, Cd 0.6 Zn 0.4 S and TCP are both n-type semiconductors .…”

“…58 To investigate the band structure of semiconductors, the flat band potentials (V fb ) of Cd 0.6 Zn 0.4 S and TCP were measured using the Mott−Schottky (M−S) experiment (Figure 8c). 59 As seen from the positive slope of M−S plots, Cd 0.6 Zn 0.4 S and TCP are both n-type semiconductors. 60 The V fb values of Cd 0.6 Zn 0.4 S and TCP are −0.53 and −1.34 V (vs. Ag/AgCl), and are further equivalent to −0.33 and −1.14 V, respectively (vs. NHE), according to eq 2.…”

Decomposition of Halogenated Molybdenum Sulfide Dianions [Mo3S7X6]2–(X = Cl, Br, I)

“…However, the nanoclusters showed reduced catalytic activity if the terminal disulfides were replaced by halogenides to form [Mo 3 S 7 Cl 6 ] 2– and [Mo 3 S 7 Br 6 ] 2– . An acid–base-resistant ligand-modified molybdenum sulfur cluster was recently reported by Zhang, Lin, and co-workers to exhibit enhanced photocatalytic HER activity …”

“…19 An acid−baseresistant ligand-modified molybdenum sulfur cluster was recently reported by Zhang, Lin, and co-workers to exhibit enhanced photocatalytic HER activity. 20 Gas-phase studies offer the advantage of dealing with welldefined and controllable systems. Such investigations give conceptual insight into the structure and behavior of individual molecules or small clusters as a model system for heterogeneous catalysis.…”

Combining Highly Dispersed Amorphous MoS3 with Pt Nanodendrites as Robust Electrocatalysts for Hydrogen Evolution Reaction

“…[13] There are also a series of MoS 2 analogues prepared according to the Müller method that mimic MoS 2 edge sites, such as [Mo 3 S 13 ] 2− , [Mo 2 S 12 ] 2− , and MoS x clusters. [14][15][16][17] Joo et al proposed that a-MoS 3 exhibits lower adsorption energy than [Mo 3 S 13 ] 2− and [Mo 2 S 12 ] 2in HER. [18] Therefore, among the MoS species, a-MoS 3 should theoretically exhibit better HER activity.…”
