Abstract

Versatile chemical reactions with the help of physical factors such as microwaves, sonic radiations, laser, elevated temperature and pressure have successfully been used to prepared silicon (high surface area), iron oxide (in amorphous and crystalline state), silver, gold, iron-platinum, cobalt-platinum nanoparticles. The microwaves fostered the chemical reactions via homogeneous and fast heating processes; the sonic radiations from an ultrasonicator created ultra-fast cooling rates at high power or just played a role of mechanical waves at low power; laser provided energy nanoparticles from bulk plates; elevated temperature and pressure produced good environments for unique reactions. All those preparation methods are simple and inexpensive but they could produce nanoparticles with interesting properties.
