Özet
In this study, orange peel (OP), one of the organic wastes, was first used as a metal-free catalyst for the production of hydrogen from sodium boron hydride (NaBH4). In order to prepare an orange peel catalyst (OP-H3PO4-Cat) with the best catalytic activity, experiments were carried out on pure orange peel with different acid types, different burning temperatures and different burning times. As a result of these experiments, it was determined that OP-H3PO4-Cat treated with 30% H3PO4 and burned at 400 degrees C for 45 min had the best catalytic activity. The OP-H3PO4-Cat material was characterised by several techniques such as FTIR, XRD and SEM. As a result, the hydrogen generation rates (HGR) at 30 degrees C and 60 degrees C in the methanolysis reaction of 2.5% NaBH4 catalysed by OP-H3PO4-Cat were found as 45,244 and 61,892 mLmin(-1)g.cat(-1), respectively. The activation energy of OP-H3PO4-Cat catalyst was calculated as 12.47 kJmol(-1). (C) 2021 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
