Nanotechnology will make human development and use of technology after the material-led, energy-led and information-led, is happening in a new era of mutual integration of the three on the basis of biotechnology and mutual integration at the nano level as the dominant.

Catalysis is a typical example of early empirical reliance on nanotechnology development. Nanoscale catalysts have many superior conditions due to the small size of nanoparticles, the large volume percent occupied by the surface, the different bonding and electronic states on the surface compared to the interior of the particles, and the incomplete number of atomic coordination on the surface.
