CatalyticApplicationsofNd-DopedZirconia:
1.OxygenStorageCapacity:
Nd-dopedzirconiapossessesexcellentoxygenstoragecapacity(OSC)duetothepresenceofoxygenvacanciesandtheabilityofNdionstoadjusttheiroxidationstate.Thispropertyisparticularlydesirableforuseinautomotivecatalyticconverters,wheretheconversionofharmfulpollutantssuchasnitrogenoxides(NOx)andcarbonmonoxide(CO)heavilyreliesontheavailabilityandstorageofoxygen.
