Robust Ru nanoparticles created by exsolution enhanced the chemical looping methane reforming performance for stable syngas production and CO2 splitting
Single Pt atom catalysts are key targets because a high exposure of substantially enhances electrocatalytic activity. In addition, PtRu alloy nanoparticles the most active for methanol oxidation reaction. To combine exceptional activity single with an Ru support we must overcome synthetic challenge forming atoms on noble metal nanoparticles. Here demonstrate process that grows and spreads islan...
Lignin obtained by hydrogenolysis of lignocellulose biomass is a prospective source valuable green fuels and chemicals such as monophenols. One the key factors in chemical decomposition lignin to monophenols an efficient catalyst. Inert porous materials hypercrosslinked polymers are suitable catalytic supports for immobilization noble transition metal nanoparticles. However, do not have acidic ...
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...
Aiming at a detailed understanding of the role of metal−support interactions in the selective methanation of CO in CO2-rich reformate gases, we have investigated the catalytic performance of a set of Ru/TiO2 catalysts with comparable Ru loading, Ru particle size, and TiO2 phase composition but very different surface areas (ranging from 20 to 235 m g−1) in this reaction. The activity for CO meth...
Stable chromium, molybdenum, tungsten, manganese, rhenium, ruthenium, osmium, cobalt, rhodium, and iridium metal nanoparticles (M-NPs) have been reproducibly obtained by facile, rapid (3 min), and energy-saving 10 W microwave irradiation (MWI) under an argon atmosphere from their metal-carbonyl precursors [M(x)(CO)(y)] in the ionic liquid (IL) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMI...
Hybridization of distinct materials into a single nanoplatform is relevant to advance material’s properties for functional application such as biosensor platform. We report the synthesis and characterization of nanosheets of graphene oxide decorated with hybrid nanoparticles of silver-ruthenium bipyridine complex (Ag@[Ru(bpy)3] ) core and chitosan shell. Hybrid nanoparticles were first obtained...
Growth mechanism of chemically-driven RuO2 nanowires is explored and used to fabricate three-dimensional RuO2 branched Au-TiO2 nanowire electrodes for the photostable solar water oxidation. For the real time structural evolution during the nanowire growth, the amorphous RuO2 precursors (Ru(OH)3 · H2O) are heated at 180 (°)C, producing the RuO2 nanoparticles with the tetragonal crystallographic ...
The performance of Ru-based nanoparticles (NPs) in the hydrogen evolution reaction (HER) relies on both their structural properties and oxidation state metal. Herein, versatility the...
