概要

The formation of vanadium pentoxide (V2O5) nanoparticles immobilized on alumina (Al2O3) particles was studied in a methane/oxygen coflow diffusion-flame reactor. V2O5 nanoparticles formed by the decomposition of vanadium oxytriethoxide were deposited onto Al2O3 particles, which were introduced into the flame together with vanadium oxytriethoxide solution. To immobilize the V2O5 nanoparticles on Al2O3 particles, rapid cooling with a Laval nozzle was applied to the V2O5/Al2O3 particles formed in the flame. We found that it was possible to suppress the sintering of V2O5 nanoparticles on the Al2O3 particles when the Al2O3 particles were introduced into the flame at a temperature sufficiently high to soften the surfaces of the Al2O3 particles.
