Tuning chemical and surface composition of nickel cobaltite-based nanocomposites through solvent and its impact on electrocatalytic activity for oxygen evolution

Annaires A. Lourenco et al.

Summary: This study investigates the influence of solvents on the impregnation of nickel ions into ZIF-67 for the synthesis of cobaltites, and explores their impact on electrocatalytic behavior. Both methanol and ethanol can form nanocomposites, but methanol experiments result in the formation of NiCo2O4/C nanocomposites, while ethanol experiments lead to the additional crystalline phase of nickel oxide (NiCo2O4/NiO/C). The NiCo2O4/C nanocomposite shows higher catalytic performance at high current densities due to low electrode resistance.

Sensing of oxidizing and reducing gases by sensors prepared using nanoscale Co3O4 powders: A study through Cu substitution

Sweta Giri et al.

Summary: We demonstrated the sensing mechanism of oxidising and reducing gases by nanoscale Co3O4 powders doped with Cu. The sensitivity towards both types of gases is attributed to the presence of Co2+ and Co3+ cations in the nearly normal spinel structure of Co3O4. The high surface area of the nanopowders exposes a higher number of octahedral Co3+ cations as adsorption sites, resulting in high sensitivity to detect -6 ppm CO in N2. The sensitivity towards O2 is affected by the presence of inactive Cu2+ at the octahedral site and the burial of Co3+ at the tetrahedral sites, reducing the adsorption sites for O2.
