Abstract

The invention provides homogeneous mesoporous metal oxide nanoenergetic composites. A composite of the invention has a regular and uniform nanostructure of metal oxide, which is structured by a surfactant. Metal fuel nanoparticles are homogenously distributed through the regular and uniform nanostructure. The invention further provides methods for making homogeneous metal oxide nanoenergetic composites. A method of the invention forms a metal oxide nanostructure via a sol-gel process with surfactant templating. Metal nanoparticles into the metal oxide nanostructure via wet impregnation.
