Facile synthesis of ultrafine Co3O4 nanocrystals embedded carbon matrices with specific skeletal structures as efficient non-enzymatic glucose sensors

Three-dimensional hierarchical meso/macroporous Fe/Co-nitrogen-doped carbon encapsulated FeCo alloy nanoparticles prepared without any template or surfactant: High-performance bifunctional oxygen electrodes

“…FeeN/PC shows a bland CV curve with the minimum background currents. However, with adding Co atoms into the catalytic systems, all Co-based samples show a pair of redox characteristic peaks for Co(II)/Co(III) between 0.9 and 1.1 V vs. RHE [45]. Specially, the peak intensities will increase with increasing the Co percentage in catalysts.…”

CuCo2O4nanowire arrays supported on carbon cloth as an efficient 3D binder-free electrode for non-enzymatic glucose sensing

“…Copper oxide 19,20 and cobalt oxide 13,21 have attracted more attention for non-enzymatic glucose sensing because of their simple synthesis process, super electrochemical property and good chemical stability. Their mixed metal oxide CuCo 2 O 4 , obtained from replacing Co 2+ in Co 2+ (Co 2 ) 3+ O 4 spinel structure with Cu 2+ , exhibits higher electrical conductivity and electrochemical activity than their monometallic oxides.…”

Synthesis of Co 3 O 4 –ZnO mixed metal oxide nanoparticles by homogeneous precipitation method

“…According to the earlier research, the physicochemical properties of the Co 3 O 4 -based materials are generally affected by their morphologies, structures, chemical composition and sizes [27,28].…”
