Hydrogen production by steam reforming of methane over Ni/ceria-zirconia : Effect of Ce/Zr content. |
| 초록 |
Steam reforming of methane (SRM) is the most common and mature method for hydrogen production. Ni/ceria-zirconia (CZ) catalysts have been studied for this reaction due to the nature to make mobile oxygen species and high reducibility of Ce–ZrO2. In addition, the interaction between the support and the nickel also has a significant impact on the activity and selectivity. In order to further understand the roles of mixed-oxide supports in the SRM, Ni/CZ catalysts with different Ce/Zr composition of support were investigated. A series of Ce-rich and Zr-rich CZ support were prepared by the citrate complex method by adjusting the Ce/Zr ratio in a range of 0.067–15. The characterizations such as surface area, reduction temperature and basicity of prepared catalysts were analyzed by BET, XRD, TPR and TPD-H2. Among the catalysts with various CZ support loading values, Ce-rich catalyst (Ce/Zr=15) exhibited the highest TPR and TPD values. |
