Highly active and stable hydrogen production by room-temperature formaldehyde oxidation on Fe2O3/Pd

Abstract

Fe₂O₃/Pd catalysts with different Pd loadings were prepared by impregnation and coprecipitation methods, and their catalytic hydrogen production performance was systematically investigated under various conditions. By optimizing the Pd loadings, formaldehyde concentration, sodium hydroxide concentration and reaction temperature, a hydrogen production rate of 293.98 mL min⁻¹ g⁻¹ over Fe₂O₃/Pd with a Pd loading of 1 wt% at 298 K can be obtained.
