Yields of (a) CH₄ and (b) CO following hydrogenation of CO₂ over Ni−Pt/Al₂O₃, as well as (c) CH₄ yield and selectivity as a function of molar Pt percentage in the NiPt alloys; m_cat = 100 mg, 10% CO₂, and 40% H₂ in He (total flow rate = 50 mL min⁻¹). (d) Illustration of the adsorbed species and the reactions taking place over Ni/Al₂O₃, the iso-Pt catalyst, and Pt/Al₂O₃ during the hydrogenation of CO₂. Reproduced with permission from [31,122].
