Recycling carbon dioxide (CO2), especially through conversion to methane (CH4), is compelling while anthropogenic CO2 emissions are still rising. A useful process for this transformation is photothermal methanation, in which CO2 and hydrogen are catalytically converted into CH4 and water upon irradiation with sunlight. In the journal Angewandte Chemie, a team of researchers has now reported the synthesis of a highly active, stable, nickel–carbon catalyst for this reaction.
