The role of different Ni sites in supported nickel catalysts for butene dimerization under industry-like conditions

Active sites for butene dimerization are single Ni n+ ( n = 1 and/or 2) moieties which are formed by oxidative addition of Brønsted sites to Ni 0 precursor species during conditioning and destroyed by reaggregation to Ni 0 clusters during deactivation. Octene is formed by subsequent insertion of but...
