Abstract: Metal-oxide composites are widely used in several fields. The recent progress of core/shell metal-oxide nano-composite materials，especially as electrodes used in solar cell，photoluminescence materials，magnetic materials，catalyst materials，sensor materials，and so on，is reviewed. Meanwhile，the future trend and problems in the application of core/shell metal-oxide nano-composite materials is also presented.
