reported nanoceria (and other metal oxides) synthesized by the
direct thermal decomposition of metal nitrates in OM [131]. Ahniyaz
et al
C [132]. They found that
the aspect ratio of the nanorods could be tuned by variation of the
reaction time; a long reaction time tends to shorten the nanorods
while does not change their diameters. They also found that when
OM was introduced, ceria nanodumbbells could be obtained.
