Macroporous silicon coated with M/TiO2 (M=Au,Pt) as a highly efficient photoreactor for hydrogen production

Macroporous silicon disks containing ordered channels of 2 µm side and 0.2 mm length (9 × 106 channels cm-2) have been functionalized with a thin layer of Au/TiO2 and Pt/TiO2 photocatalysts and tested in the photoproduction of hydrogen using UV light from water-ethanol mixtures in gas phase.
