- Abstract
Hydrogen production was studied over nickel and cobalt geothermal waste-supported catalysts. Due to their good catalytic activity, nickel, and cobalt are widely used as catalysts in ethanol steam reforming. The geothermal waste catalyst (GWC) was synthesized by hydrothermal process, then prepared using wet-impregnation with nickel nitrate and cobalt nitrate as the precursors. SEM analysis shows that nickel and cobalt successfully adhered to the GWC, which decreased the surface area. Using nickel and cobalt in ethanol steam reforming produces a higher hydrogen yield than a GWC. The best hydrogen yield was 43.04% over Ni/GWC at 550°C. Nickel can actively break C-C, OH, and C-H bonds to produce hydrogen and reduces the brønsted acid site as the carbon formation active site.
