Highly efficient electrocatalysts for overall water splitting: mesoporous CoS/MoS2with hetero-interfaces

Abstract

Mesoporous CoS/MoS2with abundant heterogeneous interfaces was faciley synthesized from a bimetallic hybrid zeolitic imidazolate framework, which showed excellent catalytic activity and reaction kinetics in both the HER and OER in 1 M KOH. Meanwhile, as a cathode and anode in water splitting electrocatalysis, it delivers a low cell voltage of 1.61 V at 10 mA cm−2and excellent durability.
