Abstract
Metal-carbon nanocomposites consisting of Fe–Co bimetallic nanoparticles uniformly dispersed in the carbon matrix were synthesized by pyrolysis of a precursor based on chitosan and metal salts in the temperature range 500–800°C. The change in the structural characteristics of the samples after activation in the presence of potassium hydroxide was studied. It was found that alkaline activation leads to an increase in the specific surface area of the nanocomposites up to 700 m2/g and in the size of metal nanoparticles, whereas the phase composition and morphology of the carbon support remain unchanged.
