Morphology-controlled synthesis of CoMoO₄ nanoarchitectures anchored on carbon cloth for high-efficiency oxygen oxidation reaction

Abstract

Novel CoMoO4 nanoarrays with different morphologies are anchored on a carbon cloth via a simple hydrothermal method by adjusting the Co/Mo atom ratio.

Spinel oxide CoFe2O4 grown on Ni foam as an efficient electrocatalyst for oxygen evolution reaction

“…The C dl value of CoFe 2 O 4 /NF (23.29 mF cm À2 ) is much higher than those of CoO x /NF (9.46 mF cm À2 ) and FeO x /NF (2.89 mF cm À2 ), indicating that CoFe 2 O 4 /NF own much higher ECSA than CoO x /NF and FeO x / NF 49. The OER catalytic performance of CoFe 2 O 4 /NF is compared with reported CoFe 2 O 4 catalysts, as in…”

One‐Step Synthesis of NiFe Layered Double Hydroxide Nanosheet Array/N‐Doped Graphite Foam Electrodes for Oxygen Evolution Reactions

“…To enhance the diffusion of liquid reactants and gas products, directly fabricating the active species with three dimensional (3D) architecture on free‐standing conductive substrates as integrated electrodes has been explored . Concomitantly, the active sites are adequately exposed by constructing 3D nanostructures; the electrochemically active surface area, penetration of electrolyte, and transportation of electron are also increased by the binder‐free characteristic . Considering these aforementioned factors, it would be of substantial significance to develop a facile and efficient strategy for loading NiFe LDHs with 3D architectures on a free‐standing nitrogen‐doped substrate for OER.…”

A flower-like CoS2/MoS2 heteronanosheet array as an active and stable electrocatalyst toward the hydrogen evolution reaction in alkaline media

“…4a), corresponding to the low energy band of Co 2p 3/2 and high energy band of Co 2p 1/2 , respectively, as well as their satellite peaks (denoted as "sat."). 39 In the Mo 3d spectrum of CoMoO 4 precursor, two signicant peaks at 232.1 and 235.3 eV are associated with Mo 3d 5/2 and Mo 3d 3/2 electronic congurations, respectively, indicating a +6 oxidation state of Mo in the CoMoO 4 NSAs (Fig. 4b).…”
