Abstract
The H2 reduced NiFe2−xCrxO4 can be used to decompose CO2 to C repeatedly. A series of nanocrystalline Ni-ferrite doping different contents of Cr3+ were synthesized by mixed ions co-precipitation method and characterized by XRD, BET and TEM. The results showed that their crystallite sizes were 1–2 nm and BET surface area changed from 220 to 285 m2/g. The evaluation of the activity and stability indicated that Ni-ferrite with 4 wt% Cr3+ dopant could be used repeatedly as many as 60 times and was transformed to FeyNi1−y (0
