Electrocatalytic Hydrogen Evolution Reaction Related to Nanochannel Materials

Abstract

Due to the high efficiency and clean process, electrocatalytic hydrogen evolution reaction (HER) is emerging as the most promising way for hydrogen (H 2 ) production, where the bottleneck is the relatively low catalytic activity for nonprecious electrocatalysts/electrodes. Currently, porous materials with channel structures show great potential toward outstanding HER performance. Herein, existing HER electrocatalysts/electrodes with 1D, 2D, and 3D channels are introduced. Recent advances as well as challenges for HER electrocatalysts/ electrodes are presented first. Then, different configuration types comprising electrocatalysts confined in inactive host porous materials, electrocatalysts directly working as host materials, and electrocatalysts confined in active host porous materials are illustrated for 1D, 2D, and 3D, respectively. Finally, the perspective for porous electrocatalysts/electrodes is discussed for future innovations of HER application.

2D FeP Nanoframe Superlattices via Space‐Confined Topochemical Transformation

“…[10] Therefore, many efforts in the field have been devoted to constructing hierarchical NC superlattices with tailored structures and morphologies, aiming to maximize mass transport and the utilization of NCs. [10][11][12][13] To this end, 2D superlattices comprised of monolayer NCs are of particular interest, because each NC component is exposed to reactants and can be readily accessed without restriction on mass transport. [14] As such, a number of techniques have been developed to construct 2D NC superlattices in the past decade.…”

“…S14, ESI †), which facilitates the kinetics towards the HER. 42 To examine the bifunctional EWS catalytic activity, the electrocatalytic OER performance of NFFeCuPt and RuO 2 catalysts 43 was also measured in 0.5 M H 2 SO 4 . As shown in Fig.…”

Valorization of the inedible pistachio shells into nanoscale transition metal and nitrogen codoped carbon-based electrocatalysts for hydrogen evolution reaction and oxygen reduction reaction

“…Despite the extraordinary advantages offered by electrolyzers and fuel cells, their commercialization is still unapproachable essentially due to the lethargic kinetics of cathodic reactions involving hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR), respectively [7,8]. To overcome the kinetic barriers for both aforementioned cathodic reactions, scarce and overpriced platinum-groupmetal (PGM) electrocatalysts are employed, constituting the key bottleneck in the given fields [9][10][11]. Furthermore, PGM electrocatalysts are also notorious for their long-term instability and least tolerance against natural contaminants (mainly anions) [7].…”
