Outline of Final Research Achievements |
Materials work in multi-component forms. A wide range of compositions must be tested to obtain the optimum composition for a specific application. We propose optimization using a series of small levitated single particles synthesized from droplets with ingredients inside. This method enables the rapid examination of the properties of particles with a wide variety of compositions. The particle composition can be controlled by merging a predetermined number of droplets containing the component materials as a solute. We aim to optimize catalytic activity of multicomponent particles which catalyze gas-phase reactions. We developed a reactivity-evaluation system of a single particle levitated in an electrodynamic trap, and measured a CO-oxidation reaction catalyzed by a single-particle catalyst of gold-supported titanium dioxide (Au/TiO2). The reactivity of the catalyst is observed from temperature rise by the heat of reaction measured by the black-body radiation.
