✦ Synopsis

The hydrogen-deuterium exchange reactions of methane in a deuterium stream were studied by a pulse experiment over a reduced nickel catalyst. The reduced nickel (Ni1373) prepared from nickel oxide calcined at 1373 K had a higher activity than the reduced nickel (Ni773) prepared from the nickel oxide calcined at 773 K. This could be due to the ratio of the Ni(1 0 0) to Ni(1 1 1). As the Ni1373 could have the surface of a higher Ni(1 0 0)/Ni(1 1 1) ratio, Ni1373 had a higher activity than Ni773.
