摘要: Sunlight-driven hydrogen production via photoreforming of aqueous solutions containing renewable compounds is an attractive option for sustainable energy generation with reduced carbon footprint. Nevertheless, the absence photocatalysts combining high efficiency and stability upon solar light activation has up to date strongly hindered development this technology. Herein, two scarcely investigated iron(III) oxide polymorphs, β- e-Fe2O3, possessing a remarkable activity in sunlight-activated H2 from oxygenates (i.e., ethanol, glycerol, glucose) are reported. For β-Fe2O3 rates 225 125 mmol h−1 m−2 obtained, significantly superior performances respect commonly α-Fe2O3.
