The role of cobalt and nickel in deoxygenation of vegetable oils

- Understanding the role of Co and Ni in hydrodeoxygenation over active phase only.
- Hydrodeoxygenation (HDO) is promoted by Ni via the Mo/Ni synergy effect on Mo edge.
- Hydrodecarbonylation (HDC) is enhanced by Co via the adsorption of C atom on S edge.
- Ni/Co-promoted MoS2 prefers different reaction routes, i.e. HDO and HDC, respectively.
- The promoting effects of Ni/Co are demonstrated by step by step reaction schemes.
