The development of catalysts for the hydrogen evolution reaction is pivotal for the hydrogen economy. Thin iron films covered with monolayer graphene exhibit outstanding catalytic activity, surpassing even that of platinum, as demonstrated by a method based on evaluating the noise in the tunnelling curr...
Here we report a hydrogen production system that combines anodic and cathodic H2 production from low-potential aldehyde oxidation and the hydrogen evolution reaction, respectively, at a low voltage of ~0.1 V. Unlike conventional aldehyde electrooxidation, in which the hydrogen atom of the aldehyde...
A hydrogen evolution reaction is the production of hydrogen through the process of water electrolysis. The evolution of hydrogen is possibly limited and based on the desorbing of molecules coming from the cathode surface. Hydrogen evolution usually occurs on metals such as: Platinum Copper Iron Moni...
The electrons in the first two conditions have no contribution to photocatalytic hydrogen evolution. Only the third type of electrons could initiate the hydrogen evolution reaction. As an auxiliary ingredient, a cocatalyst considerably inhibits the first two behaviors of electrons, thereby protecting the...

析氢反应Hydrogen Evolution Reaction,阴离子的问题 文献中常见的析氢反应方程如下 H3O+ + e− = Hads + H2O Hads+ H3O+ + e−= H2+ H2O 这是在酸性溶液中,溶液要满足电中性的话,失去正离子H+的同时也要失去同样电荷数的阴离子,这个阴离子是怎么反应的?
The hydrogen evolution reaction ( her ) was studied on bright nickel electrodes in alkaline solutions at several temperatures. The formation of nickel hydrides in the potential region of the her was previously analyzed by cyclic voltammetry and the electrode surface was pre-conditioned to minimize the...
Single-shell carbon-encapsulated iron nanoparticles: synthesis and high electrocatalytic activity for hydrogen evolution reaction Angew. Chemie Int. Ed. (2015), p. n/a-n/a, 10.1002/anie.201411450 Google Scholar [5] M. Tavakkoli, T. Kallio, O. Reynaud, A.G. Nasibulin, J. Sainio, H. ...
The hydrogen evolution reaction (HER) is a crucial step in electrochemical water splitting and demands an efficient, durable and cheap catalyst if it is to succeed in real applications1,2,3. For an energy-efficient HER, a catalyst must be able to trigger proton reduction with minimal overpotent...
