The aim of this work was to evaluate effect of different amount of rhodium used for the doping of LaFeO3prepared through solution combustion synthesis in the photocatalytic hydrogen production from glucose solution. The process efficiency was evaluated in terms of both glucose degradation and hydrogen production during the irradiation time. Characterization results showed the formation of orthorhombic perovskite type structure and the absence of rhodium oxide crystallites up to Rh loading of 1.16 mol %. Photocatalytic results showed that the highest value of H2production (1835 Î¼mol/L) was achieved on 0.70%Rh photocatalyst after 4 h irradiation time. The substitutional doping generated by the replacement of Fe4+with Rh4+promotes the separation of charge carriers efficiently, and consequently enhancing the photocatalytic activity.
