Strongly Coupled Molybdenum Carbide on Carbon Sheets as a Bifunctional Electrocatalyst for Overall Water Splitting

Abstract: High-performance and affordable electrocatalysts from earth-abundant elements are desirably pursued for water splitting involving hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Here, a bifunctional electrocatalyst of highly crystalline Mo C nanoparticles supported on carbon sheets (Mo C/CS) was designed toward overall water splitting. Owing to the highly active catalytic nature of Mo C nanoparticles, the high surface area of carbon sheets and efficient charge transfer in the strongly co… Show more

“…Nevertheless, Ni nanoparticles are prone to aggregation under typical HER and OER conditions, such as strong acid and alkali, and are prone to be corroded and passivated. [38][39][40][41][42] For instance, Kwak et al has successfully prepared Mo 2 C/carbon nanotube composites as bifunctional catalysts for both ORR and OER. [24][25][26][27] Among them, molybdenum carbide (Mo 2 C) is interesting due to its innocuous preparation process, large pH stability, and equivalent d-band electronic structure to Pt-group metals, [28][29][30][31] demonstrating a It is urgently required to develop highly efficient and stable bifunctional non-noble metal electrocatalysts for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) for water splitting.…”

“…[24][25][26][27] Among them, molybdenum carbide (Mo 2 C) is interesting due to its innocuous preparation process, large pH stability, and equivalent d-band electronic structure to Pt-group metals, [28][29][30][31] demonstrating a It is urgently required to develop highly efficient and stable bifunctional non-noble metal electrocatalysts for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) for water splitting. [39] Based on the abovementioned concepts, it is worth trying to achieve the whole water splitting through the synergistic effect between Ni and Mo 2 C electrocatalysts. Owing to the strong hydrogen binding energy on Mo 2 C and high electrical conductivity of Ni, synergetic effect between Ni and Mo 2 C nanoparticles significantly promote both HER and OER activities.…”
