Description Dehydrogenation of cyclohexane to benzene has been carried out over Ni supported on activated carbon cloth ACC (Ni/ACC)
catalysts under spray-pulsed mode reactor to study hydrogen evolution for hydrogen storage and supply system applications. The
maximum rate of hydrogen evolution using monometallic Ni/ACC catalysts was 8.5 mmol g)1
cat min)1 for Ni loading of 20% by
weight. A small amount of Pt (0.5 wt%) was added to the Ni based catalysts. A synergistic effect was observed in the case of the
promoted catalysts the hydrogen production was enhanced by ca. 1.5 times as compared to the 20 wt% Ni only catalyst. As
compared to 0.5 wt% monometallic Pt catalyst, the 20 wt% Ni–0.5 wt% Pt bimetallic catalyst exhibits ca. 60 times higher
hydrogen production rates. Selectivity towards dehydrogenation observed to be enhanced by addition of Pt into Ni/ACC catalysts.
