We report here a Cu(0)-based catalyst free of noble metals for the electrocatalytic hydrogen evolution reaction in neutral water with an onset overpotential of only 70 mV. This is the lowest reported value among Cu(0)-based catalysts for the hydrogen evolution reaction in neutral water.

Aryl-substituted tetraimine complexes related to Co(dmgBF(2))(2)(MeCN)(2) (dmg = dimethylglyoxime) were synthesized and are active for hydrogen evolution. Co(dmgBF(2))(2)(MeCN)(2) can be adsorbed to a glassy carbon electrode. The chemically modified electrode is active for hydrogen evolution in aqueous solution at pH < 4.5, with an overpotential of only 100 mV.

The need for sustainable catalysts for an efficient hydrogen evolution reaction is of significant interest for modern society. Inspired by comparable structural properties of [FeNi]-hydrogenase, here we present the natural ore pentlandite (Fe4.5Ni4.5S8) as a direct 'rock' electrode material for hydrogen evolution under acidic conditions with an overpotential of 280 mV at 10 mA cm(-2). Furthermo...

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.

The layered ternary chalcogenide, palladium phosphorous sulphide (PdPS), and its composite with reduced graphene oxide are shown to be efficient hydrogen evolution electrocatalysts. The Tafel slope and the exchange current density values associated with hydrogen evolution reaction are determined to be 46 mV dec(-1) and 1.4 × 10(-4) A cm(-2) respectively.

Efficient photocatalytic hydrogen generation in a suspension system requires a sophisticated nano-device that combines a photon absorber with effective redox catalysts. This study demonstrates an innovative molecular linking strategy for fabricating photocatalytic materials that allow effective charge separation of excited carriers, followed by efficient hydrogen evolution. The method for the s...

We have developed a computational method that predicts the positions of active compounds, making it possible to increase activity as a fragment evolution strategy. We refer to the positions of these compounds as the active position. When an active fragment compound is found, the following lead generation process is performed, primarily to increase activity. In the current method, to predict the...

For the first time, the hydrogen evolution reaction (HER) electrocatalytic performances of incompressible γ-Mo0.5W0.5C, prepared by high-pressure, high-temperature (HPHT) synthesis, were investigated in the electrolyte. The polarization curve of the γ-Mo0.5W0.5C cathode exhibits the current density of 50 mA·cm−2 at an overpotential value of 320 mV. The corresponding Tafel slope of the incompres...
