Waste-derived Pt catalysts supported on granular activated carbon were investigated for hydrogen production through glycerol aqueous phase reforming. A conventional catalyst prepared by incipient wetness impregnation was compared with a catalyst obtained by recovering platinum from waste streams through leaching and adsorption. At 290 °C and 10 barg, the waste-derived catalyst achieved glycerol conversion comparable to the reference. However, it produced less H₂ and CO₂ and more CO, highlighting the influence of preparation route on active sites, metal–support interactions and selectivity. The results demonstrate the potential of urban mining and circular catalysis for sustainable hydrogen production.

Abstract
Waste-derived Pt catalysts supported on granular activated carbon were investigated for hydrogen production through glycerol aqueous phase reforming. A conventional catalyst prepared by incipient wetness impregnation was compared with a catalyst obtained by recovering platinum from waste streams through leaching and adsorption. At 290 °C and 10 barg, the waste-derived catalyst achieved glycerol conversion comparable to the reference. However, it produced less H₂ and CO₂ and more CO, highlighting the influence of preparation route on active sites, metal–support interactions and selectivity. The results demonstrate the potential of urban mining and circular catalysis for sustainable hydrogen production.| File | Dimensione | Formato | |
