Ni(OH) nanosheets decorated with FeCoPi on NiO heterostructures: tunable intrinsic electronic structures for improved overall water splitting.

Herein, we demonstrate the rational design of 3-dimensional nickel double hydroxide nanosheets decorated with iron-cobalt phosphide on nickel oxide (Ni(OH)@FeCoPi|NiO) heterostructures for achieving improved overall water splitting. The as-optimized Ni(OH)@FeCoPi|NiO heterostructures exhibited an overpotential () of ∼133 mV and ∼173 mV at 10 mA cm for the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER), respectively, in an alkaline electrolyte through a tunable electronic interaction and stabilization of the active Ni(OH) and FeCoPi interface.

FeCoP nanosheets on NiO nanoparticles as electrocatalysts: tuning and stabilizing active sites for water splitting.

Herein, we demonstrate a novel strategy for tailoring and stabilizing the interface of active sites on hierarchical three-dimensional (3D) iron-cobalt phosphide (FeCoP) nanosheets on nickel oxide nanoparticles for overall water splitting. The developed bifunctional electrode required an overpotential of only ∼158 mV and ∼74 mV to attain 10 mA cm for oxygen evolution and hydrogen evolution reactions, respectively, with excellent durability over 100 h in 1.0 M KOH engineering interfacial active sites, revealing the progress in the development of electrocatalytic activity.

Hollow sphere nickel sulfide nanostructures-based enzyme mimic electrochemical sensor platform for lactic acid in human urine.

An enzyme-free electrochemical sensor platform is reported based on hollow sphere structured nickel sulfide (HS-NiS) nanomaterials for the sensitive lactic acid (LA) detection in human urine. Hollow sphere nickel sulfide nanostructures directly grow on the nickel foam (NiF) substrate by using facile and one-step electrochemical deposition strategy towards the electrocatalytic lactic acid oxidation and sensing for the first time. The as-developed nickel sulfide nanostructured electrode (NiF/HS-NiS) has been successfully employed as the enzyme mimic electrode towards the enhanced electrocatalytic oxidation and detection of lactic acid.
