Highly photocatalytic active thiomolybdate [Mo 3 S 13 ] 2− clusters/Bi 2 WO 6 nanocomposites

Defect Engineering of Bismuth Oxyiodide by IO3– Doping for Increasing Charge Transport in Photocatalysis

“…The Brunauer–Emmett–Teller (BET) method (ASAP 2020 V3.03 H) was used to calculate the specific surface of the photocatalysts. Electron spin resonance (ESR) tests were performed in the X-band (9.45 GHZ) at 77 K. EPR spectra of DMPO– • O 2 – (25 mM DMPO methanol solution) and DMPO– • OH (25 mM DMPO water solution) with CM–BiOI samples were detected under visible light irradiation (λ ≥ 420 nm). , A standard three-electrode configuration system was employed for the photoelectrochemical measurements where the BiOI samples, platinum plate, and an Ag/AgCl electrode (or calomel electrode) are the working, counter, and reference electrodes, respectively, using the CHI 660C electrochemical station. The electrolyte was 0.5 mol L –1 Na 2 SO 4 aqueous solution.…”

Electrocatalytic properties of {Mo3S4}-based complexes with regard to the hydrogen evolution reaction and application to PEM water electrolysis

“…44 In addition to this, the [Mo 3 S 13 ] 2À anion has been reported to be also highly HER-efficient and stable when used as co-catalyst in electrophotocatalytic devices. 45 More generally, molecular molybdenum sulphide species have been extensively studied and considered as versatile chemical platform allowing to develop multifunctional catalytic materials, such as metalsubstituted derivatives or coordination complexes, specifically designed with regard to the applied process. [46][47][48][49][50][51][52] In order to further investigate the HER properties of such class of compounds, we report herein on the development of {Mo 3 S 4 }-based molecular HER catalysts, taking benefit of the well-known chemical properties of the aqua cluster [Mo 3 S 4 (H 2 O) 9 ] 4+ , used as precursor in this work.…”

Thiomolybdate [Mo3S13]2– Nanoclusters Anchored on Reduced Graphene Oxide-Carbon Nanotube Aerogels for Efficient Electrocatalytic Hydrogen Evolution

“…This distinctive formation in [Mo 3 S 13 ] 2– makes it possible to be comparable with the expensive noble-metal catalysts, such as Pt. In addition to this, [Mo 3 S 13 ] 2– has been reported to be extremely stable when used as co-catalysts and electrocatalysts. , …”

“…In addition to this, [Mo 3 S 13 ] 2− has been reported to be extremely stable when used as co-catalysts and electrocatalysts. 32,33 Recent results demonstrated that catalyst activity for HER can be boosted by assembling them on some highly conductive nanocarbon composites, e.g., reduced graphene oxide (rGO), carbon nanotubes (CNTs), and other MoSx-carbon electrode materials. 11,24,34−39 These nanocarbons would be beneficial to the distribution of catalysts and aggrandize the conductivity of the whole catalyst.…”
