- •
GDC-coated NiO catalysts are prepared by hydrothermal synthesis.
- •
The GDC-coated NiO catalysts show high coking tolerances and catalytic activity for CH4 and CO oxidations.
- •
Direct-methane solid oxide fuel cells with the GDC-coated NiO catalyst layer are stable with high performances in CH4 for 1000 h.
- •
Covering the Ni surfaces with the GDC nano-particles may successfully suppress the growth of carbon seeds on the Ni surfaces.
