Continuous Synthesis of Surface-Modified Metal Oxide Nanoparticles Using Supercritical Methanol for Highly Stabilized Nanofluids

Abstract

The ceria nanoparticles were synthesized using supercritical methanol with decanoic acid as the surface modifier in a continuous mode. Primary particles ranging 2−3 nm were loosely aggregated and formed secondary particles with size of 30−40 nm. The nanoparticles have good dispersability in ethylene glycol.
