Molten salt electrolysis method to achieve Ni/MoS2 with activity sulfur enhance the hydrogen evolution reaction performance under alkaline condition

A facile approach to enhance the hydrogen evolution reaction of electrodeposited MoS2 in acidic solutions

“…33 The peak at 405 cm −1 corresponds to the out-of-plane vibration mode (A 1g ), in which the S atom moves in the opposite direction to the E 1 2g mode. 32,34 In addition, the slight shift and increased width of the A 1g peak in Ni–MoS 2 could be caused by reducing the number of stacked layers along the c axis. 17 Moreover, both the broadening and decreasing intensity of the E 1 2g peak in the Ni 0.05 Mo 0.95 S 2 sample imply the existence of in-plane defect sites, consistent with the XRD results.…”

“…Two strong peaks are exhibited in both samples, related to the vibration modes of the S-Mo-S layer in the 2H-MoS 2 structure. 32 The peak at 378 cm À1 corresponds to the E 1 2g mode, which represents the movement direction of S atoms opposite to Mo atoms for the in-plane vibration mode. 33 The peak at 405 cm À1 corresponds to the out-of-plane vibration mode (A 1g ), in which the S atom moves in the opposite direction to the E 1 2g mode.…”

Highly Efficient and Robust MoS2 Nanoflake-Modified-TiN-Ceramic-Membrane Electrode for Electrocatalytic Hydrogen Evolution Reaction

“…This paper takes an interest in molybdenum disulfide (MoS 2 ), which is a ubiquitous cost-effective material and well known as a significant catalyst for HER. 7,8 Due to its catalytically active metallic edges, MoS 2 displays high activity in electrocatalytic processes. 9,10 There are many catalysts which manifest high catalytic performance.…”

“…Many papers report on development of highly efficient and low-cost HER catalysts, such as metal-free catalysts and transitional metal-based catalysts (e.g., carbides, sulfides, phosphides, etc.). This paper takes an interest in molybdenum disulfide (MoS 2 ), which is a ubiquitous cost-effective material and well known as a significant catalyst for HER. , Due to its catalytically active metallic edges, MoS 2 displays high activity in electrocatalytic processes. , …”
