High-surface-area carbon aerogels are synthesized by pyrolysis of nanocellulose aerogels that are prepared by dissolving of cellulose microcrystalline in NaOH aqueous solutions followed by gelation, regeneration and freeze drying or supercritical CO2 drying. The obtained carbon aerogels are further treated via a CO2 activation process. The result shows that the nanocellulose aerogels dried by supercritical...
Transition metal phosphide (Fe 2 P, Co 2 P and Ni 12 P 5 )-doped carbon xerogels were synthesized by a one-pot pyrolysis of the sol–gel polymer of resorcinol and formaldehyde in the presence of metal nitrates and (NH 4 ) 2 HPO 4 . Various techniques, including: X-ray diffraction, N 2 adsorption–desorption, scanning electron microscopy,...
