Hollow-structured Si/SiC@C nanospheres as highly active catalysts for cycloaddition of epoxides with CO2 under mild conditions†
Abstract
Hollow-structured Si/SiC@C nanospheres were prepared through a magnesiothermic reduction of resin-coated SiO2 spheres. These nanostructured materials with high surface area not only show high adsorption capacities of industrial dyes from wastewater, but also exhibit excellent catalytic activities for chemical fixation of CO2 under mild, solvent-free conditions.
