Reports Outline Applied Ceramics Findings from King Mongkut's University of Technology (Preparation of CeO2 Nano Rods Through a Sonication-Assisted Precipitation)

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Applied Ceramics are presented in a new report. According to news reporting from Bangkok, Thailand, by VerticalNews journalists, research stated, "A CeO2 nanopowder has been synthesized using sonication-assisted precipitation. The use of ultrasonics during precipitation showed potential morphology control during synthesis."

The news correspondents obtained a quote from the research from the King Mongkut's University of Technology, "The sonication-assisted precipitation with highly aqueous base (20 M NaOH) successfully induced the formation of a one-dimensional nanostructure of CeO2 rods with a homogeneous shape and size (TEM: 24 nm diameter and 129 nm long). A conventional precipitation under the same conditions provided the CeO2 in nonuniform sizes and shapes. Heat treatment (1100 C for 4 h) was required for CeO2 formation when (NH4)(2)C2O4 was used instead of NaOH. The concentration of the precipitation agent (15-20 M) strongly affected the size and shape of the product."

According to the news reporters, the research concluded: "Importantly, according to the temperature-programmed reduction/oxidation study, the CeO2 prepared using the sonication-assisted route showed a relatively higher level of reversible oxygen storage capacity (2384 mu mol/g), compared with the CeO2 prepared by conventional route (1748 mu mol/g)."
