An Efficient Metal–Organic Framework?Derived Nickel Catalyst for the Light Driven Methanation of CO ₂

We report the synthesis of a highly active and stable metal-organic framework derived Ni-based catalyst for photothermal reduction CO2 to CH4. Through controlled pyrolysis MOF-74 (Ni), nature carbonaceous species therefore performance can be tuned. CH4 production rates 488 mmol g?1 h?1 under UV-visible-IR irradiation are achieved when is prepared optimized conditions. No particle aggregation or significant loss activity were observed after ten consecutive reaction cycles more than 12 hours continuous flow configuration. Finally, as proof-of-concept, we performed an outdoor experiment ambient solar irradiation, demonstrating potential our reduce using only energy.
