Copper nanoparticles have been grown in silica matrix by annealing of the sol–gel prepared porous matrix impregnated with the copper nitrate. The annealing has been performed in air, successively in air and hydrogen, and in hydrogen. An annealing in air results in copper oxide nanoparticles (Cu 2O)...
