Self-coupling of secondary alcohols by Ni/CeO2 catalyst

- Ni metal nanoparticles on CeO2 (Ni/CeO2) prepared by in situ H2-reduction of NiO/CeO2.
- Self-coupling of aliphatic secondary alcohols under additive free conditions in a liquid phase.
- CeO2 support and metallic Ni species are indispensable.
