Abstract
The copper/carbon support catalysts (Cu/C) were synthesized using Cattail flower as a support by the hydrothermal, impregnation and calcination processes. The effect of the Cu loading (20-60 wt.%) in impregnation method was investigated over Cu/C catalysts. The Cattail flower was pretreated by hydrothermal at 180°C for 8 h with highest specific surface area to produced support catalysts. The copper particles on support catalyst were prepared with impregnation method. The samples were compressed into pellet (diameter of 5 mm) and then calcined at 900°C for 2h under nitrogen atmosphere to obtain the copper/carbon support catalysts. The resulting samples were studied the elemental composition, morphology, and SBET by X-ray diffraction (XRD), scanning electron microscopy (SEM) with Energy dispersive X-ray (EDX), and Nitrogen sorption, respectively. The copper particles on the Cu/C catalysts were a metallic phase and high dispersion on the support surface. The Cu loading at 20 wt.% was the optimal condition because of the highest SBET. The increasing of Cu loading resulted in the SBET and particle size was decreased.
