Metal nanoparticles exhibit excellent optical, electrical, and catalytic properties corresponding bulk materials, especially their high specific surface and surface defects. Among them, the magnetic property, separation effect, and the catalytic activity during cyclic utilization of Fe3O4 nanometals are evaluated, indicating they could be used as an efficient degradation catalyst on organic reactions.1 Other hand, copper nanoparticles because of suitable properties such as easy recycling, increasing number of access to the active site and being economically are used as a catalyst in various organic reactions.2
