Hierarchical microsphere of MoNi porous nanosheets as electrocatalyst and cocatalyst for hydrogen evolution reaction

Alloying Nickel with Molybdenum Significantly Accelerates Alkaline Hydrogen Electrocatalysis

“…The increasing solution alkalinity further improves the HER activity: it now only requires −42 mV for Ni 4 Mo to reach J =10 mA cm −2 , slightly inferior to PtRu/C (−33 mV). The HER activity of our Ni 4 Mo nanoparticles exceeds all other NPM electrocatalysts under similar conditions as far as we are aware (Table S3) [37–42] . Great HER stability on RDE is also observed for Ni 4 Mo nanoparticles when biased at −50 mV in 0.1 M KOH or 1 M KOH (Figure 3 f).…”

Accelerated alkaline hydrogen evolution on M(OH)x/M-MoPOx (M = Ni, Co, Fe, Mn) electrocatalysts by coupling water dissociation and hydrogen ad-desorption steps

“…In recent few years, abundant non-noble metal-based materials have been developed as promising electrocatalysts for hydrogen evolution under alkaline conditions. 7,8 Among these transition metal catalysts, molybdenum-based compounds, 9 such as alloys, 10 carbides, [11][12][13][14][15] chalcogenides, [16][17][18] and phosphides, [19][20][21] have recently attracted signicant research interest due to their desired chemical and physical properties. For example, as a prototypical model, MoS 2 is the rst reported transition metal-based HER catalyst, in which only the surface edges are catalytically active.…”

MoS2 Nanosheets Decorated Multi‐walled Carbon Nanotube Composite Electrocatalyst for 4‐Nitrophenol Detection and Hydrogen Evolution Reaction

“…For a fixed potential of 250 mV vs RHE is applied to the composite electrode for 22 h and it produced hydrogen even after 22 h. Besides, the MWCNTs/MoS 2 electrode showed good stability even in a harsh environment. The EI spectra (Figure 6d) shows that the R ct value of MWCNTs/MoS 2 was 3.0 Ω which is lower compared to the MoS 2 (4.2 Ω) suggesting the faster HER kinetics of the composite [46].…”
