Reactions of Isobutanol over a NASICON-Type Ni-Containing Catalyst Activated by Plasma Treatments

摘要

The effect of hydrogen and argon high-frequency (HF) plasma treatment on the catalytic activity of the nickel zirconium phosphate Ni0.5Zr2(PO4)(3) in isobutanol dehydration and dehydrogenation has been investigated. The catalyst treated with H-2-HF and Ar-HF plasmas shows a similar to 2 times higher activity in both reactions. This effect is due to surface restructuring changing the number and accessibility of catalytic sites on the phosphate surface.
