Titel:
Photoelectrochemical reactivity of well-defined mesoscale gold arrays on SiO2/Si substrates in CO2-saturated aqueous electrolyte 
Abstract:
In this article we present a study on the influence of the size of mesoscopic gold nanostructures on silicon (Si) with well-defined geometry on their reactivity towards hydrogen evolution and carbon dioxide reduction. The onset potential for these two reactions decreases by 170 mV with structure size decreasing from 1400 nm to 75 nm, whereby hydrogen evolution is accelerated somewhat more than carbon dioxide reduction. This effect is independent of the doping type and level of the substrate, i.e...    »
