Claims17
A method of forming a multimetallic catalyst comprising:
- grafting an organometallic promotor comprising a metal selected from the group consisting of B, Cu, Co, Fe, Mn, Sn, Mg, V, and Zn and an organic ligand, onto a metal oxide support selected from the group consisting of Al2O3, CeO2, MgO, SiO2, and TiO2, forming a promotor-support material;
- calcine the organometallic promotor in air to form a calcined promotor-support material;
- grafting an organonickel precursor grafted onto the calcined promotor-support material;
- and
- reducing the organonickel grafted promotor-support material to form an active multimetallic catalyst.
