Nano-Ru/porous carbon composites were prepared by Ru/aerogels which were made through a reaction of resorcinol, formaldehyde and RuCl3·3H2O.
Monolithic polymer(resorcinol-formaldehyde) reinforced alumina (RF/Al2O3) aerogel composites were prepared using a sol–gel method and supercritical fluid CO2 drying.
