Design of experiments for synthesizing in situ Ni-SiO_2 and Co-SiO_2 nanocomposites by non-isothermal reduction treatment

摘要

Ni-SiO_2 and Co-SiO_2 nanocomposites were prepared by the reduction of NiCl_2- and CoCl_2-containing SiO_2 gels under non-isothermal conditions. The effect of heating rate, temperature and met~ chloride concentration were assessed using statistically planned experimental designs.
