Carbon nanotubes-molybdenum disulfide composite for enhanced hydrogen evolution reaction

Bio‐reduced GO /Pd nanocomposite as an efficient and green synthesized catalyst for hydrogen evolution reaction

“…The stability is also a critical parameter for the evaluation of the potential applications of an HER catalyst 60 . Commonly, there are two electrocatalytic methods that can be used for the stability tests; potential cycling and constant potential or current electrolysis.…”

Size-dependent trends in the hydrogen evolution activity and electronic structure of MoS2 nanotubes

“…Given that even the smallest MoS 2 nanotubes obtainable here still produced DG H ads values that were much higher than the desired thermoneutral 0 eV, this alone was unlikely to be able to explain the experimentally observed enhanced catalytic activity of the nanotubes relative to the basal plane. 35,58,59 Therefore, nanotubes with S-vacancy defects were also investigated. Previous reports on defects in MoS 2 nanotubes report Svacancies modifying the mechanical 60 and electronic or magnetic properties, 61 but the H adsorption energy has yet to be explored.…”

Size Effects of MoS2 on Hydrogen and Oxygen Evolution Reaction

“…Water electrolysis is considered as the most effective approach to generate pure hydrogen and oxygen [1][2][3][4][5][6]. Large-scale commercialization of water electrolysis is highly dependent on the development of electrocatalysts with very high efficiency, low cost, good durability and stability for the electrocatalytic water splitting [3][4][5][6][7][8][9][10][11].…”

“…Water electrolysis is considered as the most effective approach to generate pure hydrogen and oxygen [1][2][3][4][5][6]. Large-scale commercialization of water electrolysis is highly dependent on the development of electrocatalysts with very high efficiency, low cost, good durability and stability for the electrocatalytic water splitting [3][4][5][6][7][8][9][10][11]. So far, platinum-based metals have been deemed the most effective hydrogen evolution reaction (HER) catalyst and, equally, iridium and ruthenium dioxides are widely used materials as the best catalyst to accelerate oxygen evolution reaction (OER) due to their low overpotential and superior stability and catalytic activity which has already been put into practical application [2,[9][10][11][12][13][14][15][16][17][18].…”

“…In the past few years, some advances have been made by transition metal based compounds as capable of good electrocatalytic activity. Nevertheless, few of electrocatalysts possess good performance of HER and OER simultaneously [1][2][3]5]. However, two-dimensional transitional metal dichalcogenides, for example, molybdenum disulfides (MoS 2 ), tungsten disulfide (WS 2 ) and molybdenum diselenide (MoSe 2 ), had been expected to have good performance of both HER and OER [1,2,5,6].…”
