Cationic metal–organic framework derived ruthenium–copper nano-alloys in porous carbon to catalytically boost the cycle life of Li–CO2batteries

A Ru–Cu nanoalloy decorated N-doped porous carbon could be prepared based on cationic MOFs. The uniform distribution of nanoalloys in porous carbon results in an abundant accessible catalytic surface for rapid formation and decomposition of Li 2 CO 3 .
