SOLVOTHERMAL PREPARATION OF CeO2 NANOCUBES AND THEIR CATALYTIC PROPERTIES

Cubic-like CeO2 nanocrystals about 11 nm long were successfully synthesized via an ethanolamine-assisted hydrothermal route using (NH4)Ce(NO3)4 as a precursor at 180°C for 24 h. The CeO2 nanocubes were modified onto the glassy carbon electrode by adsorption to fabricate the modified electrode. The reliability and stability of the CeO2 NC/GC electrode offer a good possibility for applying the technique on routine analysis of ascorbic acid (AA) in clinical use. In addition, the catalytic effect of the CeO2 nanocubes for thermal decomposition of ammonium perchlorate (AP) was investigated by DTA and TG. The catalytic performance of CeO2 nanocubes is superior to that of commercial CeO2 powder.
