Enhanced Hydrogen Evolution
MoS2 nanoflowers are successfully decorated on cobalt‐containing nitrogen‐doped carbon nanotubes to form dual‐active domains (Co‐NCNTs/MoS2). The coupling of featured domains optimizes the electronic structure and triggers the bifunctional effect to balance the Volmer step, thereby increasing the reaction step efficiency and leading to a high hydrogen evolution catalytic...
The reaction kinetics of hydrogen evolution reaction (HER) is largely determined by balancing the Volmer step in alkaline media. Bifunctionality as a proposed strategy can divide the work of water dissociation and intermediates (OH* and H*) adsorption/desorption. However, sluggish OH* desorption plagues water re‐adsorption, which leads to poisoning effects of active sites. Some active sites may even...
