“…It showed that the dried gel was mainly composed of Mo and S, and the mole ratio of S/Mo is 4.0 (Mo: 43.52 wt%, S: 56.39 wt%). This result implied that the composition of the molybdenum polysulfide gel could be written as ''Mo 3 S 12 '', which was also mentioned by Hibble et al [17]. In this transformation process, one-thirteenth of the sulfur in (NH 4 ) 2 Mo 3 S 13 was lost, the new generating cluster ''Mo 3 S 12 '' was insoluble in formamide solution.…”

“…Depending on the orientation of the supported clusters (insets are shown in Figure 3 a), we can identify a number of triangular formations, which suggests the intact structure of the {Mo 3 } cluster cores upon binding, in line with their high structural stability. 36 Figure 3 b shows a high-resolution image of an area with relatively higher Mo/S concentrations according to EDS signal. It reveals an assembly of bright spots organized in chain-like meta-structures, as highlighted by circled regions in the filtered image.…”

Surface Anchoring and Active Sites of [Mo₃S₁₃]^2– Clusters as Co-Catalysts for Photocatalytic Hydrogen Evolution

Achieving light-driven splitting of water with high efficiency remains a challenging task on the way to solar fuel exploration. In this work, to combine the advantages of heterogeneous and homogeneous photosystems, we covalently anchor noble-metal- and carbon-free thiomolybdate [Mo 3 S 13 ] 2– clusters onto photoactive metal oxide supports to act as molecular co-catalysts for photocatalytic water splitting. We demonstrate that strong and surface-limited binding of the [Mo 3 S 13 ] 2– to the oxide surfaces takes place. The attachment involves the loss of the majority of the terminal S 2 2– groups, upon which Mo–O–Ti bonds with the hydroxylated TiO 2 surface are established. The heterogenized [Mo 3 S 13 ] 2– clusters are active and stable co-catalysts for the light-driven hydrogen evolution reaction (HER) with performance close to the level of the benchmark Pt. Optimal HER rates are achieved for 2 wt % cluster loadings, which we relate to the accessibility of the TiO 2 surface required for efficient hole scavenging. We further elucidate the active HER sites by applying thermal post-treatments in air and N 2 . Our data demonstrate the importance of the trinuclear core of the [Mo 3 S 13 ] 2– cluster and suggest bridging S 2 2– and vacant coordination sites at the Mo centers as likely HER active sites. This work provides a prime example for the successful heterogenization of an inorganic molecular cluster as a co-catalyst for light-driven HER and gives the incentive to explore other thio(oxo)metalates.

Transition metal dichalcogenides (TMDC) have been identified as excellent platforms for developing the next-generation commercial flexible logic devices and sensors, owing to their outstanding mechanical, optical, and electrical properties. The TMDCs can be used to produce novel form-factors for wearable electronic devices. Typically, synthesis of large-scale TMDC thin film have been achieved by complexity vacuum-based approach. Therefore, it is essential to develop a simple and effective method to boost-up mass production of TMDC thin films on a large scale upon arbitrary substrates. In this regard, the solution-based TMDC synthesis method is advantageous because it proposes a simplification of the fabrication processes and an easy scaling-up of the material with a non-vacuum system. In this review, we summarize the evolution of the solution-based thin-film preparation and synthesis of the TMDCs; subsequently, we discuss the merits and drawbacks of the recently developed methods to form TMDC thin films directly from the deposited precursor. Finally, we discuss the practical applications of the TMDC thin films, which demonstrate the feasibility of their commercialized applications in electronic devices and sensors.
