Enhanced oxygen storage capacity of Ce0.65Hf0.25M0.1O2-δ (M = rare earth elements): Applications to methane steam reforming with high coking resistance

- CeO2-HfO2 based materials were newly synthesized and characterized using a number of analytical techniques.
- The redoxability and size of the dopants were proposed to play a pivotal role in enhancing the OSC of the materials.
- Ni/Ce0.65Hf0.25Pr0.1O2 showed significantly enhanced stability for steam reforming of methane by suppressing carbon coking.
