Nanoscale, zero-valent iron is a promising reagent for in situ reduction of a variety of subsurface contaminants, but its utility in full-scale remediation projects is limited by material costs. Iron nanoparticles (20-100 nm diameter) supported on carbon (C-Fe0) were synthesized by reacting iron salts, adsorbed or impregnated from aqueous solutions onto 80 m2/g carbon black, at 600-800 degrees ...

Ceramic-based absorbing composite is irreplaceable in high-temperature conditions. This work has fabricated a novel biomass–derived porous SiCnw/SiC for structure–function integrated electromagnetic wave (EMW) absorption through selective laser sintering (SLS) 3D printing and carbothermal reduction. SLS processed the biomass-derived wood precursor with unique microstructures. The properties wer...

With the view to improve densification behaviour and mechanical properties of ZrB2-SiC ceramics, three synthesis routes were investigated for production ZrB2, prior fabrication ZrB2-20 vol. % SiC via spark plasma sintering (SPS). Two borothermal reduction routes, modified with a water-washing stage (BRW) partial solid solution Ti (BRS), utilised, alongside boro/carbothermal mechanism (BRCR) uti...

The development of strategies for the sustainable management and valorization agricultural waste is outmost importance. With this in mind, we report use rice husk (RH) as feedstock preparation heterogeneous catalysts hydrogenation reactions. were prepared by impregnating milled RH with a silver nitrate solution followed carbothermal reduction. composition morphology fully assessed IR, AAS, ICP-...

This study investigates the effects of the addition of tungsten on the structure, phase composition, textural properties and activities of β-SiC-based catalysts in the aqueous phase hydrogenation of furfural. Carbothermal reduction of SiO₂ in the presence of WO₃ at 1550 °C in argon resulted in the formation of WxC-β-SiC nanocomposite powders with significant variations in particle morphology an...
