Cobalt borides are known to be exceptionally resistant to oxidation, a chemical property which makes them useful in the field of materials science. For instance, studies suggest cobalt boride can increase the lifespan of metal parts when used as a coating, imparting surfaces with higher corrosion and wear resistance.

2016年1月7日 · It is demonstrated that amorphous cobalt boride (Co 2 B) prepared by the chemical reduction of CoCl 2 using NaBH 4 is an exceptionally efficient electrocatalyst for the oxygen evolution reaction (OER) in alkaline electrolytes and is simultaneously active for catalyzing the hydrogen evolution reaction (HER).

2021年10月19日 · This boride-derived oxide catalyzes oxygen evolution with an overpotential of 167 mV at 10 mA/cm 2 in 1 M KOH electrolyte and requires a record-low overpotential of 460 mV to maintain water ...

2015年4月1日 · This work presents Cobalt-Boride (Co–B) as a non-noble, efficient and robust electrocatalyst for Hydrogen Evolution Reaction (HER) active in aqueous solution of wide pH values. In neutral solution, amorphous Co–B nanoparticles (30–50 nm size) generate high current density (10 mA/cm 2 ) at low overpotential (250 mV) with Tafel slope of 75 ...

2023年4月1日 · Cobalt boride as an electrocatalyst for water splitting is a promising material for achieving efficient performance. In this study, cobalt boride nanoparticles with high crystallinity were synthesized under tens of nanometers by thermal plasma.

2025年3月26日 · The amorphous cobalt-boride (CoB) has put on display a unique “reverse electron transfer” mechanism where boron, although more electronegative, transfers electrons to cobalt. Nevertheless, CoB is not able to produce activity similar to noble metals, and thus, continued research and optimization of CoB is required to close the performance ...

2019年7月2日 · This study provides a unique method for the rapid deposition of amorphous Co−B nanosheets on Ni foam (Co−B/NF) by alternatively dipping Ni foam into cobalt salt and borohydride solutions. The as-prepared Co−B/NF can act as a highly efficient electrocatalyst for the oxygen evolution reaction (OER).

We describe a very efficient and stable bifunctional electrocatalytic system for reversible oxygen electrodes obtained by direct CVD growth of nitrogen-doped carbon nanotubes (NCNTs) on the surface of cobalt boride (CoB) nanoparticles.
