CO-tolerant RuNi/TiO2 catalyst for the storage and purification of crude hydrogen

Nature Communications, 2022
Efficient storage of crude hydrogen, through toluene hydrogenation to methylcyclohexane, is often inhibited by CO impurities. Here, the authors develop a RuNi/TiO2 catalyst which avoids deactivation through promoting simultaneous CO methanation.
