Abstract

A mesoporous Fe-Ni catalyst was prepared by microwave combustion method by using glycine as a fuel to help the combustion occur in the microwave. The bimetallic catalyst synthesized was intend to accelerate the production of hydrogen via decomposition of formic acid. The hydrogen produced supposedly can substitute the energy source used now especially from fossil fuels to contribute to the reduction of greenhouse effect. The catalyst sample was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and N2 adsorption-desorption isotherm (BET). From the BET isotherms, a type IV isotherm was observed, indicate the presence of mesoporous solid. XRD diffractograms of Fe-Ni have well-defined diffraction patterns with strong and sharp diffraction peaks, indicating that they are crystalline. The SEM images show the presence of voids and pores in the sample and spongy structure which also consisted of very fine crystalline. The selectivity for H2 formation using the prepared bimetallic catalyst was achieved ranging of 94 to 99% for 120 minutes at optimum conversion of formic acid and merely at room temperature.
