Descrição: dc.descriptionNi(OH)2 loaded on Ni-doped d-FeOOH photocatalysts were prepared by a simple and low-cost one-step precipitation method. The effect of Ni(OH)2 nanoparticles and Ni2+ doping on the photocatalytic hydrogen production rates by d-FeOOH in aqueous suspension was investigated. The results showed that the photocatalytic H2-production activity of d-FeOOH was significantly enhanced by doping with Ni2+ ions and by loading Ni(OH)2 on its surface. The maximum H2-production was obtained for the sample with 20 wt% Ni, which provided 5746 mmol h 1 g 1. This high photocatalytic H2-production is due to the combined effects of Ni2+ doping and Ni(OH)2 loaded on the d-FeOOH surface. The Ni2+ doping increased the conductivity and charge transfer in d-FeOOH, whereas the Ni(OH)2 improved the charge separation in the d-FeOOH and, consequently, the photocatalytic H2-production activity.-
