Crude glycerol valorization by Aqueous Phase Reforming on Waste-derived platinum-based catalysts

This work reports selected results from the DURABLE project (PRIN 2022PNRR), based on carbonsupported platinum catalysts obtained via urban mining for hydrogen production via glycerol APR. A granular activated carbon (Norit® GCN 1240) was used both as a conventional support for platinum deposition by incipient wetness impregnation (IWI), serving as a reference catalyst, and as a sorbent for platinum recovery from waste streams through a real leaching-adsorption process, yielding a WDC derived from secondary sources such as automotive spent catalysts. These two preparation approaches were designed to enable direct comparison between conventionally synthesized and waste-derived catalytic systems, highlighting the impact of the recovery strategy on catalyst properties and performance.
