Developing new methods
of catalyst preparation is one of the most
important tasks in the field of catalysis. A simple one-tube vapor
deposition (VD) is provided in this paper for preparing the supported
Ni catalyst. Ni(acac)2 was used as the Ni precursor. This
preparation method was successfully applied to three types of catalytic
supports, that is, Al2O3 and zeolites 5A and
Hβ. Varying Ni contents of less than 8 wt % can be obtained
by employing different conditions. The Ni content, depending on different
deposition conditions, was preliminarily explored. The catalytic performance
for oxidative dehydrogenation of ethane (ODHE) was tested for the
prepared Ni catalysts by the VD method. Several cases of catalytic
tests showed that for the same Ni content, the VD-prepared Ni catalyst
presented better performance for ODHE than the one prepared by a traditional
impregnation method. Besides the improvement in catalytic performance,
several advantages of our VD preparation method for catalysis are
discussed.
