Small amounts of SO3H-functionalised room temperature synthesized ionic liquids efficiently dehydrate aqueous xylose to furfural under microwave heating at mild reaction conditions. The RT-ionic liquid catalysts were also found be effective for the two step one-pot simultaneous hydrolysis and dehydration a lignocellulosic waste biorefinery-derived syrup enriched in C5 sugar oligomers.
The implementation of sodium-ion batteries for renewable energy storage requires the development sustainable electrode materials. Usually, these materials are produced through complex energy-intensive processes that challenging to scale and involve expensive and/or toxic reagents. In this study, hard carbon materials, some doped with iron, synthesized from sucrose using a simple, fast, cost-effective two-step eco-friendly process, investigated as anodes batteries. influence physicochemical...
Carbon-supported Pd nanoparticles have been proved to be efficient dual hydrogenation–oxidation nanocatalysts in both the selective aqueous oxidation of benzyl alcohol and hydrogenation furfural water under microwave irradiation. Nanocatalysts based on trioctylphosphine triphenylphosphine-stabilized-Pd NPs oxidized carbon support were found most active. The presence oxygen groups surface support, particularly those acidic character, improve immobilization as well affinity, consequently...
Abstract Supported single atoms constitute excellent models for understanding heterogenous catalysis and have achieved breakthroughs during the past years. How to prevent aggregation modulate activity of these species via metal‐support interaction should be considered practical applications. This work presents simple methods involving creation carbon‐ (on carbon nanotube (CNT)) or oxygen‐vacancies TiO 2 ) stabilize nickel ruthenium atoms. The defective supports resulting catalysts are...
Graphite materials were prepared from two Spanish anthracites, AF and ATO, by heating at different temperatures within the range 2000−2800 °C. XRD Raman spectroscopy employed to characterize degrees of crystallinity crystal orientation materials. In addition studying evolution typical parameters such as interlayer spacing, d002, crystallite sizes, La Lc, with temperature, this work aimed evaluate influence elemental composition, texture (as measured optical microscopy), mineral matter raw...
The purpose of this research was to study the influence temperature, treatment time, and initial coal particle size on evolution structural order graphite materials that have been prepared from an anthracite at temperatures >2273 K. Crystalline parameters such as interlayer spacing crystallite sizes were calculated X-ray diffractometry measurements. analysis first- second-order Raman spectra allowed assessment degree orientation outermost layers these materials. graphitization happened in...
The graphitization process of two different carbonized anthracites in the temperature interval 2000−2800 °C was studied by using optical properties materials prepared. These are defined main axes ( , and ) parameters (Rev, Rst, Ram) reflectance-indicating surface (RIS) anisotropy indexes (BW oil bireflectance ratio). Two segments, with second one being a plateau, were found to occur evolution structural organization (textural anisotropy) materials. variation order as determined from X-ray...
