Low‑Temperature CH4 Reforming and Water Splitting with Activated NiO/CeO2 as Oxygen Carrier (IMAGE)
Caption
- Low-temperature (≤600 °C) CH4 activation and high syngas selectivity (>98.5%, H2/CO2) were simultaneously achieved using the activated NiO/cCeO2 oxygen carrier. Nearly pure H2 was produced during the water splitting step.
- Synergistic advantages of low operating temperature and high selectivity significantly enhance the energy efficiency of chemical looping CH4 reforming and water splitting process.
- Precise control over the size and density of Ni sites and activation and structural evolution of NiO/cCeO2 were systematically investigated.
