| Abstract: | “Nanomania” has reached the area of heterogeneous catalysis, therefore, a new concept namely called nanocatalysis is generated. Firstly, the importance and essence of nanocatalysis is illuminated from such aspects as size, composition and morphology of nanoparticles. Subsequently, two preparation methods including microemulsion and sol-gel methods of nanocatalysts and their applications are reviewed. Advances in physical methods for characterizing the structure and composition of nanoparticles are contributing to a molecular-level understanding of their structure-performance relationships. |

| Keywords: | nanocatalysis microemulsion sol-gel method characterization |
