- ПубликацияТолько метаданныеSynthesis and characterization of Pt-HxMoO3 catalysts for CO-tolerant PEMFCs(2022) Kurdin, K. A.; Sinitsyn, V. V.; Galitskaya, E. A.; Filatova, E. A.; Kuznetsov, V. V.; Кузнецов, Виталий Владимирович© 2020 Elsevier B.V.Two relatively simple synthetic procedures were developed for the synthesis of Pt–HxMoO3 composites. The obtained materials may be of interest as CO-tolerant catalysts for hydrogen-air fuel cells with proton-exchange membranes (PEMFCs). The first step of both syntheses was to prepare hydrogen molybdenum bronzes (HxMoO3) through the addition of Zn powder to acidic solutions containing Mo(VI) species. Two types of hydrogen-containing molybdenum bronzes were synthesized, namely, red bronze (x≈1.55) and green bronze (x≈2.0). The next step was the Pt deposition in a redox reaction between HxMoO3 and potassium tetrachloroplatinate (K2PtCl4) under open-circuit conditions that resulted in composite materials defined by aPt⋅b(HxMoO3). Numerous physical methods, including XRD, STEM, SEM, and XPS, were used to determine both the composition and structure of the catalysts. Platinum clusters were distributed over the surface of catalytically active support (HxMoO3) in both cases; however, the type of molybdenum bronze used for synthesis affects the size of Pt particles. Linear sweep voltammetry (LSV) was used to determine the regularities of both adsorbed carbon monoxide electrodesorption and dissolved CO electrooxidation. CO-tolerance of prepared composites was estimated using H2/100 ppm CO mixture under conditions of both an electrochemical cell and a membrane electrode assembly (MEA). The results of this work are promising, as they provide a relatively simple method for the synthesis of CO-tolerant catalysts. The understanding of the origin of the CO-tolerance is essential for the development of electrode materials that could be used in the real fuel cells.
- ПубликацияТолько метаданныеAn effective electrochemical destruction of non-ionic surfactants on bismuth-modified lead dioxide anodes for wastewater pretreatment(2020) Kuznetsov, V. V.; Kapustin, E. S.; Pirogov, A. V.; Kurdin, K. A.; Кузнецов, Виталий ВладимировичNon-ionic surfactants are permanent components of wastewater of various origins, and their removal is necessary for sewage treatment. A new method of electrochemical treatment of wastewater for non-ionic surfactant destruction has been proposed. Effective destruction of both alkoxylated and phenoxylated non-ionic surfactants was performed using beta-Pb1-xBixO2-0.5x anodes prepared by electrodeposition. The method proposed is based on the generation of active oxygen-containing species (e.g., OH center dot, HO2 center dot) at the anode followed by chemical interaction between these radicals and organic molecules, which results in the destruction of pollutants. Oxide materials obtained by electrodeposition contained similar to 4.5 % of bismuth and have the beta-PbO2 lattice. The insertion of bismuth into the composition of lead dioxide prepared by electrodeposition resulted in an increase in their specific surface area from 0.66 to 2.5 m(2) g(-1). Modification of beta-PbO2 by bismuth led to the shift of oxygen evolution potentials toward more positive values. Effective electrooxidation of non-ionic surfactants was achieved in the solutions exposed to electrochemical treatment. There were no accumulations of metabolites in the solutions during electrolysis. Chemical oxygen demand decreased from 80 to 5 mg O-2 dm(-3), and total organic carbon (TOC) decreased from 24 to 1.5 ppm during 1 h of the electrochemical treatment. The electrode material was stable under electrolysis conditions. No accumulation of both lead and bismuth species in the solution under electrochemical treatment was found.
