Abstract

Abstract This study reports the activity of cobalt based metal oxide electrode with spinel structure for 5-hydroxymethylfurfural (HMF) oxidation. For that purpose, the Co3O4 and NiCo2O4 electrode with filamentous nanoarchitecture were grown on Ni foam by a hydrothermal method and then characterized by means of SEM, TEM, and XPS analyses. During electrochemical oxidation of HMF, the role of Co3+ in Co3O4 and NiCo2O4 spinel structure was investigated by XANES. The filamentous nanoarchitecture of NiCo2O4 showed 99.6% 5-hydroxymethylfurfural (HMF) conversion efficiency with 90.8% selectivity on 2,5-furandicarboxylic acid (FDCA). The catalyst was successfully recycled up to three times, retaining over 80% of FDCA conversion efficiency. These results demonstrated the potential interest of NiCo2O4 anodic catalyst, prepared via hydrothermal method, for production of high-valued chemical from biomass-derived compounds via electrochemical techniques.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
