Abstract

In this study, a highly efficient method was developed for the growth of carbon nano-onions (CNOs) in open air by effectively coupling the laser energy into the combustion flames through the resonant excitation of C 2H4 molecules. CNOs with concentric graphitic shells were obtained at the wavelength of 10.532 μm compared with those grown without laser. The growth rate of CNOs at the wavelength of 10.532 μm is 2.1 g/h. Laser scattering during the synthetic process indicates the formation of the CNOs is ascribed to the direct decomposition of the C2H4 molecules into solid carbons on surfaces of growing particles.
