Co‐doped CeO2 nanorodsmodified GC electrodenitrobenzeneCeO2 nanoparticles (CNPs), Co-doped CeO2 nanoparticles (CCNPs) and Co-doped CeO2 nanorods (CCNRs) were synthesized by simple co-precipitation method and explored their sensing behaviour towards nitrobenzene. XRD and TEM analysis confirmed the ...
Transition metal (Co, Cu, Fe)-doped CeO 2 catalysts with three-dimensional mesoporous channels had been synthesized through a nanocasting route using three-dimensional mesoporous silica KIT-6 as the template. All four catalysts exhibited high surface area (>120m 2 g 1 ) and ordered mesopore. ...
It was found that the Cr-doped CeO 2 nanorods show superior CO oxidation activity than the pristine counterparts (CeO 2 nanorods and Cr 2 O 3 ). The highest CO oxidation efficiency was achieved with the light-off temperature of T 50 =261°C, when the Cr doping amount was 10% (Ce ...
In this paper, the room temperature ferromagnetism of rf sputtered Co doped CeO2thin films is reported whereas undoped CeO2thin films exhibit paramagnetic behavior. The ferromagnetic properties of the Co doped films were explained based on oxygen vacancies created by Co ions in Ce sites. This is...
