Boosting CO hydrogenation towards C₂₊ hydrocarbons over interfacial TiO_2-x/Ni catalysts.

ABSTRACT: Considerable attention has been drawn to tune the geometric and electronic structure of interfacial catalysts via modulating strong metal-support interactions (SMSI). Herein, we report the construction of a series of TiO_2-x/Ni catalysts, where disordered TiO_2-x overlayers immobilized onto the surface of Ni nanoparticles (~20 nm) are successfully engineered with SMSI effect. The optimal TiO_2-x/Ni catalyst shows a CO conversion of ~19.8% in Fischer-Tropsch synthesis (FTS) process under atmospheric pressure at 220 °C. More importantly, ~64.6% of the product is C₂₊ paraffins, which is in sharp contrast to the result of the conventional Ni catalyst with the main product being methane.
