Study of the synthesis of CeO2 nanoparticles for their use in CO preferential oxidation (COPrOx)

- Ceria nanoparticles were synthesized by a simple, easy to scale-up method.
- The effect of EG and TMAH on particle and crystallite size was studied.
- Complete elimination of nitrates and organic matter could be achieved at 500 °C.
- The activity of ceria nanoparticles in COPrOx depends on calcination temperature.
- Samples pretreated at 500 °C presented high conversions at the lowest temperature.
