Ultrafine β-SiC with high surface area (150 m2 g−1) has been synthesized by inflight processing of charred rice husk in a r.f. plasma reactor operating at atmospheric pressure. The plasma-synthesized particles were doped with platinum (1%) and tested as a catalytic support material. The catalyst (1% Pt doped β-SiC) showed 100% conversion of CO to CO2 at a temperature as low as 175°C. 
Nanoporous silicon carbide as nickel support for the carbon dioxide reforming of methane
Fumed silica is used as a template in the nanocasting approach towards nanoporous silicon carbide, and it can then be applied as a catalyst support. By varying the pyrolysis temperature between 1000
Nanoporous and highly active silicon carbide supported CeO₂-catalysts for the methane oxidation reaction.
The synthesis scheme using core-shell particles is suited to functionalize silicon carbide with a high degree of stabilization of the active nanoparticles against sintering in the core of the template even at pyrolysis temperatures of 1300 °C rendering the novel synthesis principle as an attractive approach for a wide range of catalytic reactions.
