TL;DR: Ammonium tetrathiomolybdate (ATM) is found to be a novel electrode material forming self-assembled adlayers on Au electrodes which are robust and stable in aqueous environments as discussed by the authors.
Abstract: Ammonium tetrathiomolybdate (ATM) is found to be a novel electrode material forming self-assembled adlayers on Au electrodes which are robust and stable in aqueous environments. Iron–porphyrin catalysts can be physiadsorbed on this electrode material and these modified electrodes are quite stable during hydrodynamic electrochemical experiments unlike self-assembled monolayers (SAMs) of thiols on Au/Ag. The rate of interfacial charge transfer can be tuned by controlling the height of the ATM assembly by varying the deposition time. These electrodes allow convenient tuning of the electrokinetics of 4e−/4H+ O2 reduction from mass transfer to charge transfer with the same electrode material.

Abstract: The invention provides a preparation method for carbon-supported monolayer molybdenum disulfide composite catalyst for low-temperature hydro-conversion of carbonyl sulfide, which belongs to the technical field of functional catalytic material preparation and environment-friendly catalytic application. Ammonium tetrathiomolybdate is uniformly dispersed on a surfactant-modified appropriate carbon source, and hydrazine hydrate liquid-phase reduction and high-temperature treatment are then performed, so that the carbon-supported monolayer molybdenum disulfide composite material is obtained. In the material, monolayer molybdenum disulfide uniformly grows on the surface of carbon support, the material shows property rich in defective and active sites, and shows excellent activity in catalytic conversion of carbonyl sulfide by hydrogenation, and the catalytic performance is stable. The preparation method is easy to operate, the cost is low, the temperature of catalysis is low, the accuracy of catalysis is high, the stability is good, and the invention has good economic benefit and industrial application prospect.
