Renewable decyl-alcohol templated synthesis of Si-Cu core-shell nanocomposite

Monodispersed silica spheres with particles size of ca. 450 nm were successfully synthesized using a modified St�ber method. The synthesized monodispersed silica spheres were successfully coated with copper using modified sol-gel method employing nonsurfactant surface modifiers and catalyst. A renew...
