초록
We investigated NiFe2O4/Ce0.9Gd0.1O1.95 (GDC) composites as oxygen carrier materials for chemical looping hydrogenproduction (CLHP). CLHP is a promising technology to simultaneously capture carbon dioxide and produce hydrogen fromfossil fuels. We found that increasing GDC content increased the amount of the hydrogen production of NiFe2O4/GDCcomposites. Moreover, the oxygen transfer rate for the re-dox reaction increased significantly with increasing GDC content. GDC may affect the reaction kinetics of NiFe2O4/GDC composites. The finely dispersed GDC particles on the surface ofNiFe2O4 can increase the surface adsorption of reaction gases due to the oxygen vacancies on the surface of GDC, and enlargethe active sites by suppressing the grain growth of NiFe2O4. The NiFe2O4/15wt% GDC composite showed no significantdegradation in the oxygen transfer capacity and reaction rate during several re-dox cycles. The calculated amount of hydrogenproduction for the NiFe2O4/15wt% GDC composite would be 2,702 L/day per unit mass (kg).
