英文摘要silica-supported zr-doped cobalt ferrite complex oxides, co1-2xzrxfe2o4/sio2 (0 <= x <= 0.15) were prepared via a simple sol-gel auto-combustion method using aqueous silica colloid as the silica source. the products were used as reactive materials in two-step thermochemical cycles for co2 splitting. compared to undoped cobalt ferrite, the zr-doped ones can significantly enhance the rates of the reduction and oxidation steps as well as the yields of co. the zr-doped sample also showed greater recyclability than the undoped one. when the sample co0.8zr0.1fe2o4/sio2 was used as reactive material, the average production of 24.4 ml/g(ferrite) for o-2 and 40.2 ml/g(ferrite) for co were obtained after 20 cycles at 1400 and 1100 degrees c respectively. a kinetic analysis indicated the apparent activation energy in the co2 splitting step over co0.8zr0.1fe2o4/sio2 is 118.0 +/- 1.2 kj/mol, while it is 133.0 +/- 2.1 kj/mol for cofe2o4/sio2.
