Monodispersed spheres of Si-Cu core-shell nanocomposite with silica as core and copper as shell were successfully synthesized by a modified two-step synthesis method. Spherical particles of silica core were first synthesized using a modified St�ber method using nonsurfactant template. The obtained m...
