Abstract

original image

Solar Fuels: Different n- and p-type semiconductors have been investigated for sustainable solar fuel production. p-Type semiconductors, such as NiO, Fe3O4, Co3O4, and CuO, are able to reduce carbon monoxide by water or hydrogen to methane (see picture). The highest CH4 yield achieved was 17.26 mmol of CH4 per gram of catalyst using NiO in an excess of H2.
