A MoS2-Co9S8-NC heterostructure as an efficient bifunctional electrocatalyst towards hydrogen and oxygen evolution reaction

Highly efficient electrocatalysts for overall water splitting: mesoporous CoS/MoS2 with hetero-interfaces

“…[7][8][9][10] As consequence, many excellent transition-metal-based electrocatalyst, such as carbides, oxides, phosphides, nitrides, and sulfides, have been synthesized by scientists which showed excellent electrocatalytic performance with different structural and catalytic characters. [11][12][13][14] Among them, transition metal sulfides, such as MoS 2 and CoS based hybrids have been widely studied as HER and OER electrocatalysts for their low cost and high activity. [15][16][17][18] Recently, some binary sulfides have been assembled as bifunctional electrocatalyst and applied in symmetric electrode electrolyzer, showing excellent catalytic activities.…”

Nitrogen-Doped Mixed-Phase Cobalt Nanocatalyst Derived from a Trinuclear Mixed-Valence Cobalt(III)/Cobalt(II) Complex for High-Performance Oxygen Evolution Reaction

“…36 1 shows a higher photocurrent for OER, but for N@MPCoNC, the dark current dominates, indicating its particular suitability as an electrocatalyst for OER. N@MPCoNC exhibits higher electrocatalytic currents for OER because of the presence of active sites for electrochemical OER 87 whereas 1 displays comparatively low electrocatalytic currents but higher photocurrents with respect to N@MPCoNC, which may indicate a lower intrinsic conductivity but lower recombination and enhanced charge separation in 1. 88,89 The electrocatalytic photocatalytic currents and onset potentials of OER by using our catalyst are comparable and better than those of several reported catalytic systems.…”

Strategies to improve electrocatalytic and photocatalytic performance of two-dimensional materials for hydrogen evolution reaction

“…The fabrication of heterostructured composites is an efficient method to improve the activity of MoS2 [189][190][191]. Although Co doping can significantly improve the HER performance of MoS2, its activity is still far below the theoretical HER activity of MoS2.…”
