N-doped carbon anchored CoS(2)/MoS(2) nanosheets as efficient electrocatalysts for overall water splitting

The oriented two-dimensional porous nitrogen-doped carbon embedded with CoS(2) and MoS(2) nanosheets is a highly efficient bifunctional electrocatalyst. The hierarchical structure ensures fast mass transfer capacity in improving the electrocatalytic activity. And the greatly increased specific surfa...

description The oriented two-dimensional porous nitrogen-doped carbon embedded with CoS(2) and MoS(2) nanosheets is a highly efficient bifunctional electrocatalyst. The hierarchical structure ensures fast mass transfer capacity in improving the electrocatalytic activity. And the greatly increased specific surface area is beneficial to expose more electrocatalytically active atoms. For oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) tests in 1 mol/L KOH solution, only 194 and 140 mV overpotential are required to achieve a current density of 10 mA/cm(2), respectively. Our research provides an effective strategy for synergizing the individual components in nanostructures for a wide range of electrocatalytic reactions.
