One-pot Synthesis of Mo2N/NC Catalysts with Enhanced Electrocatalytic Activity for Hydrogen Evolution Reaction

Facile synthesis of molybdenum carbide nanoparticles in situ decorated on nitrogen-doped porous carbons for hydrogen evolution reaction

“…4 d) are fitted into several species. For Mo 2 N/NC, the peak at 228.6 eV can be ascribed to Mo 2 N, and the other peaks are related to different oxidation states of molybdenum, such as MoO 2 and MoO 3 [16,35] . For Mo 2 C/NC, the fitted peaks located at the binding energy of 228.5 and 231.8 eV are associated to the Mo 2 C, and the other peaks are defined to molybdenum oxides with different oxidation states [38,40] .…”

“…Recently, transition metal-based materials, especially molybdenum (Mo)-based compounds, such as carbides, phosphides, nitrides and borides have been believed as the promising alternatives to replace noble metal electrocatalysts for cathodic HER, owing to their low-cost and fascinating physical/chemical properties [13][14][15][16][17] . Specially, Mo-based compounds are able to catalyze HER with high intrinsic activity in alkaline and acidic medium.…”

Facile synthesis of Mo2C nanoparticles on N-doped carbon nanotubes with enhanced electrocatalytic activity for hydrogen evolution and oxygen reduction reactions

“…The first stage has a step at 360 °C, which indicates that the Mo 2 C is oxidized to MoO 2 in the air; continue to heat up to reach the second stage, reappeared a step at 470 °C, which indicates that the MoO 2 is further oxidized to MoO 3 [42] . After that, the weights decrease because of the burn of CNTs until 550 °C, then the curves tend to steady and the weights reach to a constant, which means that the CNTs are completely burned and the remnant is MoO 3 [43] . Calculated through Eq.…”
