Evaluation of hydrogen evolution reaction activity of molybdenum nitride thin films on their nitrogen content

Revealing the activity of Co3Mo3N and Co3Mo3N0.5 as electrocatalysts for the hydrogen evolution reaction

“…This suggests that the lower nitrogen content in Co 3 Mo 3 N 0.5 is responsible for the instability of the catalyst which is in line with the behaviour previously reported in the binary Mo-N system. 13 LSV data also show that performance deteriorates aer 1000 cycles in Co 3 Mo 3 N 0.5 (Fig. S7 †) while the activity of Co 3 Mo 3 N remains unchanged (Fig.…”

“…[9][10][11][12] This limitation may be overcome by employing ternary nitrides instead of alloys, as a recent report demonstrated the superior stability of binary molybdenum nitrides over Mo metal in acidic conditions. 13 Remarkably, ternary nitrides have remained relatively unexplored as electrocatalysts in acidic media up to date (Table S1 †) and those nitrides that had delivered OVPs in the vicinity of 100 mV at 10 mA cm À2 were generally synthesized with poorly dened crystal structure and compositions. Many investigated nitride catalysts contained impurity phases and/or were composite materials, with for example, high surface area metalfoam or carbons.…”

Ru doped molybdenum-based nanowire arrays for efficient hydrogen evolution over a broad pH range

“…Hydrogen energy has been recognized as a potential energy source owing to its high energy density, rich earth reserves and renewable ability. 1 Electrochemical water splitting is an economically feasible hydrogen production strategy, which consists of the cathodic hydrogen evolution reaction (HER) and the anodic oxygen evolution reaction (OER). At present, the HER is a mature technology in the investigation of electrochemical water splitting, and is expected to achieve zero carbon emission in the process of energy conversion to solve environmental problems, and thereby highly active and low-cost catalysts are urgently required to increase the kinetics of the HER process.…”

MoS2 with Controlled Thickness for Electrocatalytic Hydrogen Evolution

“…Platinum (Pt)-based noble metal catalysts have shown strong catalytic activity, but their higher prices and lower reserves have prevented them from being applied in industry [7]. Therefore, exploring and developing non-noble metal catalysts with abundant reserves, low price, high efficiency and durability is an important strategy to promote the application of hydrogen energy, which has become one of the most important research hotspots [8][9][10].…”
