Low-cost semiconductor photocatalysts that can efficiently harvest solar energy and generate H2 from water or biofuels will be critical to future hydrogen economies. Here, we evaluate the performance of low-cost Ni/TiO2 photocatalysts (Ni loadings 0–4wt.%) for H2 production from ethanol–water mixtures (0–100vol.% EtOH) under UV excitation. Ni(II) was deposited on P25 TiO2 by the complex precipitation...
This paper systematically compares the activity of Au/TiO 2 photocatalysts (Au loadings 0–10wt.%) for H 2 production from ethanol–water mixtures under UV excitation. Degussa P25 TiO 2 was used as the support phase. TEM analyses revealed that the average Au nanoparticle size at all loadings was 5±2nm, with the Au nanoparticles preferentially located at the interfacial sites...
