Abstract

Ni-doped FeP/carbon hollow nanorods exhibit excellent electrocatalytic hydrogen evolution performance over the full pH range.

Pore Surface Engineering of Covalent Triazine Frameworks@MoS2 Electrocatalyst for the Hydrogen Evolution Reaction

“…It is evident that there are no variationso f BET surface area of CTFs when the thiourea was absent in the reactions ystem;t he calculated BET surface areas is 1578 m 2 g À1 .A st he MoS 2 formed into/onto the bulk CTFs, the microporous channels were blockeda nd then the BET surface area sharply decreased to 389 m 2 g À1 with thiourea added. [26] The morphology of as-prepared CTFs@MoS 2 -X was investigated by SEM, as shown in Figure2.D istinct layers stackinga rchitecturew ere observed in Figure 2a,w hichi ndicated the high crystal quality of CTFs was obtained under high temperature ionothermal conditions. As the additive amount increased to 1:1, a large proportion of mesopores or macropores were present on the external surfaceo fC TFs, which were caused by the interparticlev oids from MoS 2 nanoparticles.…”

Hierarchically Porous W‐Doped CoP Nanoflake Arrays as Highly Efficient and Stable Electrocatalyst for pH‐Universal Hydrogen Evolution

“…In recent years, heteroatom doping has demonstrated as one of most effective ways to enhance the intrinsic catalytic activity of TMPs by modulating their electronic conductivity and electronic structures . For example, Sun and coworkers presented that Mn‐doped Ni 2 P nanosheets show enhanced HER performance in alkaline electrolyte, which is due to the Mn doping can remarkably improve the electronic conductivity of Ni 2 P. Lu et al reported that Ni‐doped FeP/C hollow nanorods show improved catalytic activity in pH‐universal electrolytes. Density functional theory (DFT) calculation further suggests that the enhanced catalytic activity for HER benefits from the synergistic modulation of the electronic properties and active components.…”

Construction of Hierarchical Co–Fe Oxyphosphide Microtubes for Electrocatalytic Overall Water Splitting

“…[11,12] Apart from the well-studied metal oxides and (oxy)hydroxides, [9,[13][14][15] transition metal sulfides, [10,16] phosphides, [17,18] carbides, [19,20] and selenides, [21,22] have been proved as efficient earth-abundant electrocatalysts toward water splitting. [24,25] Compared with phosphides with single metal cations, mixedmetal phosphides exhibit outstanding performance as a result of the synergistic effect of different components. [23] During electrocatalytic water splitting, phosphorus in metal phosphides would be able to participate in the reaction through moderate bonding to the reaction intermediates and create surface with proton acceptor and hydride acceptor sites, leading to high activity.…”
