AbstractAn effect of heat treatment conditions (convective, resistive heating) was considered on the composition and surface properties of FeCrAl wire used as a catalyst for methane decomposition. It was shown that resistive heating is a more effective method for activating the FeCrAl wire catalyst, which promotes the dispersion of iron-enriched pa...

AbstractPublished data on experimental and theoretical studies of systems for long-term storage and transportation of hydrogen, based on liquid organic hydrogen carriers operating in hydrogenation–dehydrogenation cycles, are reviewed. Comparative analysis of the hydrogen capacity and hydrogenation–dehydrogenation conditions was made for various cla...

AbstractA novel compound (DOPO-V-PA) containing phosphorus and silicon elements was grafted onto the surface of graphene oxide (GO) to obtain a graphene-based flame retardant (GO–DOPO-V-PA). The structure of GO-DOPO-V-PA was characterized and confirmed by FTIR and XPS spectra. AFM measurements showed that the average height of GO-DOPO-V-PA was thic...

AbstractMixed nickel-cobalt oxide was prepared by hydrothermal synthesis. The morphology and structure of the produced oxide were studied using scanning electron microscopy and X-ray structural analysis: spinel NiCo2O4 forms spherical nanostructures. Electrodes were prepared from composite materials based on nickel-cobalt mixed oxides, polyvinylide...

AbstractA series of synthesized photostabilizers were used for modification of amine-curable epoxy compounds. The effect of various modifiers on the mechanical and decorative properties and adhesion of coatings based on the model paint-and-varnish compounds in the course of aging was studied. The photostabilizers synthesized do not appreciably affe...

AbstractTwo types of treatment of the initial mechanical mixture [silicon nanopowder and graphene oxide (GO)] for obtaining Si/RGO nanocomposites were used: reduction in hydrazine vapor and heat treatment at 550°C in an argon atmosphere. It was shown that the type of reduction has an influence on the morphological and electrochemical characteristic...

AbstractThe reactions of intermetallic compounds ACo3 (A = Ce, Y) with hydrogen and ammonia at 20–450°C were studied. The composition of the products and the conditions for preparing the hydride and nitride phases were determined. Phase transformations in the ACo3–NH3 system in the temperature interval 20–450°C and the general scheme of hydrogenati...

AbstractIn this paper, we investigate the exergy analysis of the combustion chamber supplied by different fuel compositions based mainly on methane and/or hydrogen in order to select the optimum fuel composition case for the economic combustion. For this, the analysis process considers the variation for both parameters: mass flow rate and equivalen...

AbstractA catalyst (PWG) with glycine modified phosphotungstic acid was synthesized, and used in the process of oxidative desulfurization. FT-IR, XRD and SEM were used to perform the characteristic of PWG particle. And then, the desulfurization of simulated oil was tested by adding PWG, acetonitrile and hydrogen peroxide in it with synergistic reac...

AbstractZinc oxide nanoparticles were co-doped with varying concentrations of lanthanum (La) and cerium (Ce) ions using co-precipitation method. The resulting powders were calcined in a muffle furnace for 1 h at a temperature of 500°C to produce La,Ce-doped ZnO nanoparticles of varying stoichiometry viz. (Zn0.98La0.01Ce0.01O, Zn0.96La0.02Ce0.02O, Z...
