英文摘要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 TiO2-x/Ni catalysts, where disordered TiO2-x overlayers immobilized onto the surface of Ni nanoparticles (similar to 20 nm) are successfully engineered with SMSI effect. The optimal TiO2-x/Ni catalyst shows a CO conversion of similar to 19.8% in Fischer-Tropsch synthesis (FTS) process under atmospheric pressure at 220 degrees C. More importantly, similar to 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. A combination study of advanced electron microscopy, multiple in-situ spectroscopic characterizations, and density functional theory calculations indicates the presence of Ni delta-/TiO2-x interfacial sites, which could bind carbon atom strongly, inhibit methane formation and facilitate the C-C chain propagation, lead to the production of C2+ hydrocarbon on Ni surface.
