An apparatus for forming a C1 to C5 oxygenate from carbon dioxide and a C1 to C4 hydrocarbon is described. The apparatus comprises: a dielectric barrier discharge, DBD, device arranged to generate a plasma; and a passageway having an inlet for the carbon dioxide and the C1 to C4 hydrocarbon and an outlet for the oxygenates. In one example the passageway includes therein a catalyst. The passageway extends, at least in part, through the DBD device wherein, in use, the carbon dioxide in reacted with the C1 to C4 hydrocarbon in the generated plasma, thereby forming the oxygenates from at least some of the carbon dioxide and the C1 to C4 hydrocarbon. The DBD device comprises a conducting liquid as a ground electrode. A method and a use are also described.
