Manganese oxide nanoparticles have many possible applications including gas sensors, catalysts, airborne agent traps to name a few. These nanoparticles have distinct advantages over bulk counterparts for these applications due to unique magnetic properties, and enhanced surface-to-volume ratio. Herein we report a simple, one-pot synthesis method for the preparation of MnO nanoparticles in pure single phase with monodespersity. Although bulk MnO is antiferromagnetic, their nanoparticles show very interesting paramagnetic properties. The possible mechanism will be discussed.
