Photothermal Catalysis: Photothermal Catalyst Engineering: Hydrogenation of Gaseous CO2 with High Activity and Tailored Selectivity (Adv. Sci. 10/2017)

The size dependence of the photothermal effect of palladium nanocrystals enables the selectivity of the solar powered heterogeneous catalytic hydrogenation of carbon dioxide to be finely tailored towards producing either carbon monoxide through the reverse water gas shift reaction, CO2 + H2 → CO + H2O, favored for small nanocrystals or to methane, via the Sabatier methanation reaction, CO2 + 4H2 → CH4 + 2H2O, preferred for larger nanocrystals. This is described by Geoffrey A. Ozin and co‐workers in article number 1700252.
