Single-atom alloy Ir/Ni catalyst boosts CO2 methanation via mechanochemistry

A new catalytic approach is pioneered to achieve CO2 methanation via a single atom alloy Ir/Ni catalyst using a ball-milling method. This Ir/Ni catalyst exhibits a TOFCH4 of 10244 h−1 and a 220 h lifetime at 350 °C without deactivation, illustrating excellent catalytic efficiency in the presence of...

Zusammenfassung:A new catalytic approach is pioneered to achieve CO2 methanation via a single atom alloy Ir/Ni catalyst using a ball-milling method. This Ir/Ni catalyst exhibits a TOFCH4 of 10244 h−1 and a 220 h lifetime at 350 °C without deactivation, illustrating excellent catalytic efficiency in the presence of mechanical energy.
