Natural gas is a potent greenhouse but remains an attractive energy resource for good number of reasons. Because complementing the use natural with carbon dioxide capture and storage yields several drawbacks, producing synthetic instead could be interesting alternative. Methanation established well-known process, atmospheric as input it deliver climate-neutral carrier, which we refer to renewab...

In this study, two Ru/TiO2 samples with different TiO2 facets were prepared to investigate their photo-thermal catalytic CO2 + H2 reaction behavior. Without UV irradiation, the 67% {001} facet (3RT) displayed improved thermal activity for methanation than that of 30% (0RT). After pretreatment, both exhibited enhanced activities, but H2-treated 3RT (3RT-H) superior 0RT (0RT-H). Under 3RT-H appar...

A series of nickel-cerium-promoted mesoporous silica (SBA-15) catalysts modified with different loadings yttrium were synthesized by cetyltrimethylammonium bromide (CTAB)-assisted impregnation. The tested in CO2 methanation reaction and characterized N2 sorption, X-ray fluorescence (XRF), small-angle scattering (SAXS) wide-angle diffraction (XRD), H2 chemisorption, transmission electron microsc...
