“…It has been reported that the addition of V and Mo oxides into the Pt catalyst usually increases the methanol electrooxidation activity by the synergistic effect between Pt and the oxides promoters [24,25,28,46]; so, the V and Mo atoms in the PMV may easily activate the water to form oxygen-containing species at lower potential which is necessary for the oxidation of CO-intermediate and then enhances the methanol electrooxidation similarly via the bi-functional mechanism of PtRu. In the present work, the PMV modified Pt electrode exhibited better performance for methanol electrooxidation than PMA modified Pt electrode.…”

“…It has been reported that transition metal oxides (VO x and MoO x ) in combination with Pt-based catalyst can greatly promote CO oxidation due to the formation of oxygen-containing species at a low potential [24][25][26][27][28][29]. Therefore, it can be inferred that, from the above reports, the combination of transition metals oxides and HPA should promote the electrooxidation of methanol.…”

“…Besides Mo x W 1– x O 3 , the successful synthesis of other Mo-based mixed oxides has also been reported, such as Mo x Re 1– x O 3 and Mo x Se 1– x O y . These ternary oxides are a group of substitutional solid solution formed by replacing some solvent atoms with solute atoms.…”

A novel method involving the fabrication of Mo-W mixed oxide (MoWO) is proposed to modify the modest reaction kinetics and poor cycling stability of MoO material. By a simple coelectrodeposition method, a series of MoWO oxides is deposited on a TiO nanotube array substrate. Because of the differences between Mo and W in nature, there is significant distortion existing in the mixed oxides, leading to their decreased crystallite size and enlarged lattice space, which facilitates ion diffusion in the solid. As results, the mixed oxides show much better balance between specific capacitance and cycling stability than the bare MoO or WO sample, which suffers from either poor cycling stability or low electrochemical activity. Impressively, the optimal Mo-W mixed oxide exhibits a high specific capacitance of 517.4 F g at 1 A g, and, moreover, it retains 89.3% of the capacitance even at a high current density of 10 A g, demonstrating ultrahigh rate capability. These findings reveal the potential of the Mo-W mixed oxide for constructing advanced ultrahigh power supercapacitors.

“…Analysis of all known methods of obtaining thin layers of rhenium chalcogenides showed clearly that the electrochemical method is the most promising and economical [6][7][8][9][10][11][12]. Therefore, the search and development of new electrochemistry related techniques to produce thin semiconductor films of rhenium chalcogenides on various substrates including metal substrates, is considered not only practically, but also theoretically relevant [13][14][15][16][17][18].…”

Based on the study of volt-ampere dependencies during electroreduction of rhenium (VII), tellurium (IV) and copper (II) ions from hydrochloric acid electrolyte on Pt electrode, the conditions of deposition of nano-coatings of ternary Re-Te-Cu alloy were determined. The influence of various factors such as amounts of individual components and total concentrations of components in the electrolyte solution, temperature, concentration of hydrochloric acid, etc., on the composition and quality of coatings was studied. It was established that with the increase of rhenium concentration in the electrolyte, as well as increase of temperature, the rhenium content in deposits increased. The morphology of films deposited on platinum substrate was studied using the scanning electron microscopy. Based on the experimental data, the following electrolyte composition (mol/l) is recommended for obtaining the semiconductor Re-Te-Cu alloy containing 40-50 wt.% Re: (6.9·10-4-6.9·10-3) KReO4 + (9·10-4-1.8·10-2) TeO2 + (6·10-4-1.2·10-2) CuCl2·2H2O +2 HCl, T = 75 °C.
