Abstract
A study was conducted to demonstrate a clean, gas-phase approach, to synthesize tunable compositions of bimetallic nanoparticles at constant particle size. A continuous-flow atmospheric pressure microplasma reactor was used to decompose organometallic precursors and prepare narrow dispersions of bimetallic nanoparticles in a single step. Carbon nanotube (CNT) growth was achieved by mixing the particle-laden flow exiting the microplasma reactor with acetylene and hydrogen gas and heating in a tubular flow furnace. The flow system was integrated with aerosol instrumentation to watch CNT nucleation and growth and relate the catalytic properties of bimetallic nanoparticles to CNT growth. Kinetic investigations were performed, to obtain activation energies, as a function of particle composition.
