Molybdenum diselenide – black phosphorus heterostructures for electrocatalytic hydrogen evolution

Scalable Synthesis of a MoS2/Black Phosphorus Heterostructure for pH‐Universal Hydrogen Evolution Catalysis

“…As compared to the EEBP, A g 2 and B 2g vibration modes of MoS 2 /EEBP hybrid show the Raman peaks shifted to lower wavenumbers on account of vibrations inhibition, suggesting an intimately interfacial interaction between EEBP and MoS 2 . [21,22,27] Besides, increased A 1g mode intensity demonstrates more edge-terminated S sites, since the A 1g mode stands for the out of plane vibration of S atoms which are in opposite directions (along the c-axis). [28] The peak intensity ratio of E 2g 1 to A 1g can indicate the edge-exposed degree of MoS 2 .…”

“…[20] Analogously by van der Waals (vdW) interaction, Wan et al fabricated a MoSe 2 /LEBP heterostructure with enhanced electrocatalytic properties for HER (η 10, 380 mV). [21] Instead of the weak vdW interaction, a further improvement was illustrated by Vishnoi et al by using a covalently linked phosphorene-MoS 2 /MoSe 2 heterostructure for HER (η 10, 330 mV). [22] This clearly features that the increase of interactive strength between BP and TMDs could effectively promote the HER electrocatalytic properties.…”

Recent Advances on Black Phosphorus Based Electrocatalysts for Water‐Splitting

“…The obvious electron density variations between BP and MoSe 2 in the heterostructure produced an enhanced HER activity than individual constituents (either BP or MoSe 2 alone). [50] These heterostructures were constructed via van der Waals interaction between BP and MoS 2 as well as MoSe 2 . [46,50] BP could also be covalently cross-linked with MoS 2 and MoSe 2 , respectively, as efficient HER electrocatalysts.…”
