Synthesis and Characterization of Ni-Doped Carbon Aerogels

Abstract:

The carbon aerogels doped with nickel were produced by sol-gel, supercritical ethanol drying, and high-temperature carbonization, using resorcinol-furfural as carbon source, nickel nitrate as nickel source, absolute ethanol as dispersion medium, 1,2-epoxypropane as gel initiator, polyacrylic acid as the chelating agent. The carbon aerogels were characterized by nitrogen adsorption and XRD. The effects of the molar ratio of 1,2-epoxypropane to nickel on porosity of the Ni-doped carbon aerogels were investigated. It is found that the Ni-doped carbon aerogels have abundant mesopores and the doped nickel is dispersed in samples in metallic state and oxide or pure metal depending on the preparation conditions. The mesopore volume and average mesopore size all increase with the ratio of 1,2-epoxypropane to nickel.
