Development of efficient, affordable, non-precious metal oxides catalysts is critical for the oxygen evolution reaction (OER). Herein, we present a spinel NiCo2O4 nanowire arrays (NWAs), synthesized by a simple solution route, as an inexpensive, efficient anode electrocatalyst for water electrolysis. The as-prepared NiCo2O4 NWAs contains Ni2+/Ni3+ which replace Co in octahedral sites of the spinel...
Uniform nickel nanoparticles were applied to improve the sensitivity of sensors for phenobarbital (PB) determination. A Ni nanoparticle-modified imprinted electrochemical sensor was developed by thermal polymerization with the use of methacrylic acid as the functional monomer and ethylene glycol maleic rosinate acrylate as the crosslinking agent. The chemical structures and morphologies of the imprinted...
