Aqueous phase reforming of glycerol over Pt/<scp>NiAl<sub>2</sub>O<sub>4</sub></scp> catalyst
Abstract Glycerol hydrogen production by aqueous phase reforming (APR) has been shown to be an efficient method of treating glycerol, which is an abundant by‐product of biodiesel production. This study investigates the APR of glycerol using a Pt/NiAl 2 O 4 catalyst, aiming to develop a sustainable method for hydrogen production from biodiesel byproducts. In comparison with traditional supports, NiAl 2 O 4 provides improved thermal stability and resistance to phase transformation. Characterization techniques have revealed that the NiAl 2 O 4 support enhances the dispersion and stability of Pt particles, contributing to a glycerol conversion into gaseous products of 99.9% and a lifespan of longer than 530 hours (only 2% loss). Reaction pathways were explored, suggesting that Pt/NiAl 2 O 4 effectively promotes both dehydrogenation and water‐gas shift reactions, thereby highlighting its potential for APR applications in bio‐hydrogen production.
