Although intensive efforts have been made and great progress has achieved relating to the electrocatalytic hydrogen evolution reaction (HER), an advanced synthesis strategy for efficient electrocatalyst is still most significant goal.

Replacement of precious platinum with efficient and low-cost catalysts for electrocatalytic hydrogen evolution at low overpotentials holds tremendous promise for clean energy devices. Here we report a novel type of robust cobalt-nitrogen/carbon catalyst for the hydrogen evolution reaction (HER) that is prepared by the pyrolysis of cobalt-N4 macrocycles or cobalt/o-phenylenediamine composites an...

In this experimental study, we investigate various transition-metal silicides as platinum-group-metal-(PGM)-free electrocatalysts for the hydrogen oxidation reaction (HOR), and for the hydrogen evolution reaction (HER) in acidic environment for the first time. Using cyclic voltammetry in 0.1 M HClO₄, we first demonstrate that the tested materials exhibit sufficient stability against dissolution...

Molybdenum sulfide is considered to be an alternative material commercial platinum catalysts for electrocatalytic hydrogen evolution reaction (HER). 1T-MoS2 has higher hydrophilicity and electronic conductivity than 2H-MoS2 is...

With the socio economic development, people have paid more and more attention to energy source problems, especially to clean and renewable energy such as hydrogen. It is appealing but still challenging to find or design an appropriate catalyst which is inexpensive and efficient for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in the same electrolyte. In this wo...

Hydrogen production through electrochemical water splitting has gained significant attention owing to its environmental benefits over traditional methods. However, designing an efficient electrocatalyst for the hydrogen evolution reaction (HER) in alkaline electrolyte remains a challenge. In this study, colloidal Pd‐doped Ni2P nanoparticles were prepared via thermal decomposition‐based strategy...

Molecular hydrogen (H 2 ) production by electrochemical evolution reaction (HER) is being actively explored for non-precious-metal based electrocatalysts that are earth-abundant and low cost like MoS . Although it acid-stable,...

An unprecedented combination of porous SWCNHs with tetradentate polypyridine cobalt( ii ) complexes bearing pyrene groups has been realized to produce a hybrid cathode active for the hydrogen evolution reaction (HER) in water at neutral pH.

Hydrogen evolution reaction (HER) by electrochemical water splitting using new promising non-precious metal catalysts shows great potential for clean energy technology. The design and fabrication of a high-performance electrode material based on cobalt disulfide/reduced graphene oxide (CoS2/RGO) nanocomposites is reported by a one-step hydrothermal method. Benefiting from its structural advanta...
