A particularly significant route currently being developed for CO 2 utilization is catalytic CO 2 hydrogenation. Instead of using H 2 , direct conversion of CO 2 with CH 4 (dry reforming of methane, DRM) to liquid fuels and chemicals (e.g. acetic acid) represents another promising route for both CO 2 valorisation and CH 4 activation.
