title: Visible-light photocatalytic conversion of carbon monoxide to methane by nickel(II) oxide.
abstract: Solar Fuels: Different n- and p-type semiconductors have been investigated for sustainable solar fuel production. p-Type semiconductors, such as NiO, Fe3 O4 , Co3 O4 , and CuO, are able to reduce carbon monoxide by water or hydrogen to methane. The highest CH4 yield achieved was 17.26 mmol of CH4 per gram of catalyst using NiO in an excess of H2 .
