For small Pt nanoparticles (NPs), catalytic activity is, as observed, adversely affected by size in the 1–3 nm range. We elucidate, via first-principles-based thermodynamics, the operation H* distribution and cyclic voltammetry (CV) during the hydrogen evolution reaction (HER) across the electrochemical potential, including the underpotential region (U ≤ 0) that is difficult to assess in experi...

Hydrogen evolution reaction (HER) involving electrocatalytic process is established as a promising and non-pollution method for hydrogen production. The cheap alternatives of precious-metal electrocatalysts with high activity robust stability essential the high-scale application evolution. Recently, carbon-based derived from biomass have attracted more attentions thanks to their characteristics...

The Front Cover shows how metals with more destabilized interfacial water molecules could behave as efficient electrocatalysts for hydrogen evolution reaction (HER) where high rate, despite of relatively activation energy, is possible to achieve via values preexponential factor by proton tunnelling. While destabilization the proton's solvation sphere in acidic electrolytes intuitive, alkaline m...

The electrochemical generation of hydrogen fuel via the proton reduction in the Hydrogen Evolution Reaction (HER) in aqueous media is currently dependent on the use expensive noble metal catalysts for which alternatives must be sought. Molybdenum disulfide (MoS₂) has shown great promise as a suitable electrocatalyst in this regard. While many lab-scale experiments on the HER activity of this ma...

Hydrogen fuel is regarded as the future clean energy alternative to fossil fuels. Water electrolysis has been touted a key technology component in realizing hydrogen economy. The electrocatalytic evolution reaction (HER), fundamental step water electrolysis, therefore subject of immense investigation. In particular, search for low-cost and catalytically active HER electrocatalyst remains at for...

A hydrogen bond-driven supramolecular strategy to synthesize multiphase-Fe anchoring on hierarchical N-doped graphitic carbon was proposed. As a result, the as-obtained catalysts showed unusual trifunctional activities in the oxygen reduction reaction, oxygen evolution reaction and hydrogen evolution reaction, even surpassing noble-metal catalysts such as Pt/C and RuO2.

Tungsten trioxide nanorods have been generated by the thermal decomposition (450 C) of tetrabutylammonium decatungstate. The synthesized tungsten trioxide (WO3) nanorods have been characterized by XRD, Raman, SEM, TEM, HRTEM and cyclic voltammetry. High resolution transmission electron microscopy and X-ray diffraction analysis showed that the synthesized WO3 nanorods are crystalline in nature w...

The scalable and sustainable production of hydrogen fuel through water splitting demands efficient and robust Earth-abundant catalysts for the hydrogen evolution reaction (HER). Building on promising metal compounds with high HER catalytic activity, such as pyrite structure cobalt disulphide (CoS2), and substituting non-metal elements to tune the hydrogen adsorption free energy could lead to fu...

The in situ surface reconstitution of a catalyst for hydrogen evolution refers to its structure induced by strong interactions with reaction intermediates during the (HER), which eventually leads self-optimization active sites. In consideration superior performance that can be achieved reconstitution, more and attention has been paid relationship between site HER activity. More and/or operando ...

Molybdenum disulfide (MoS2) has been widely examined as a catalyst containing no precious metals for the hydrogen evolution reaction (HER); however, these examinations have utilized synthesized MoS2 because the pristine MoS2 mineral is known to be a poor catalyst. The fundamental challenge with pristine MoS2 is the inert HER activity of the predominant (0001) basal surface plane. In order to ac...
