Preparation of Pd-doped carbon aerogel powder with radiation method
Pd-doped carbon aerogel powder is prepared with radiation method in 100, 200 and 500 kGy radiation doses, which has been confirmed by XRD, SEM and energy spectrum test. The SEM images show that Pd is well distributed in all the surface of aerogel particles. The nitrogen adsorption data analysis shows that the specific surface area, average pore diameter and total pore volume of carbon aerogel powder all decrease obviously after Pd doping. As the reduced metal mostly decorates the outer surface of the carbon aerogel powder, the textural parameters of doped carbon aerogel powder in different radiation doses are close to each other.
