Abstract:Herein, we show that coupling boron with cobalt oxide tunes its structure and significantly boost its electrocatalytic performance for the oxygen evolution reaction (OER). Through a simple precipitation and thermal treatment process, a series of Co−B oxides with tunable morphologies and textural parameters were prepared. Detailed structural analysis supported first the formation of an disordered and partially amorphous material with nanosized Co3BO5 and/or Co2B2O6 being present on the local atomic scale. The b… Show more
“…TMOs have been widely used as electrode materials because they meet the standards of elemental abundance, catalytic activity, and stability, especially in alkaline environments. 91 Among various TMO materials, Co based TMOs have been regarded as promising non-precious metal OER and HER electrocatalysts for water splitting. 92,93 The use of Co based MOFs as sacrificial templates is a good way for the construction of Co based TMOs, because it is easy to regulate the morphology and incorporate additional elements during the derivative process to further tune the catalytic activity.…”

“…Since water splitting is a thermodynamically unfavored process, it was further affected by the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in the higher overpotential regions. 3,4 In the case of overall water splitting process, it is necessary to bring down the overpotentials of both the aforementioned reactions. 5 So, an electrocatalyst plays a remarkable role in catalyzing these reactions in a lower overpotential region.…”
