Double Templates Synthesis of Mesoporous Materials

In recent years, synthesis and characterization of ordered nanomaterials with high specific surface area have received increasing interest because of their potential applications in catalysis, selective separation and electrochemical devices such as batteries, fuel cells and supercapacitors.  With the development of self-assemble nanotechniques, template synthesis was paid much attention as a new kind of fabricated technology of ordered nanomaterials. The corresponding template can be looked as a nanoscopic reactor for the synthesis of nanoarrays of the desired materials such as metal, metal oxide, non-metal and so on by chemical or physical method. Therefore, structure of mesoporous ordered nanomaterials can be controlled easily and effectively by template synthesis. In the candidates of templates family, porous anodic aluminum oxide template as a hard template and the lyotropic liquid crystalline phase of surfactant as a soft template are most widely used to prepare ordered nanomaterials among the templates to fabricate nanostructure products due to the rich polymorphism and long-range periodicities of porous structures.
