Synthesis of ultrathin porous C3N4-modified Co3O4 nanosheets for enhanced oxygen evolution reaction
Abstract
Abstract Oxygen evolution reaction (OER) plays important roles in energy storage and conversion technologies, but the sluggish kinetics of OER may result in a large overpotential, and thus there is urgent need for the exploration of new electrocatalysts with a low overpotential and good stability. In this research, we integrate the melamine-assisted alkaline cobalt carbonate (CoCH) nanosheets pyrolysis with high-temperature solid phase fusion to construct the 1-C3N4/Co3O4/Ni foam hybrid electrode with Co3O4 ultrathin porous nanosheets as the host, trace C3N4 as the guest, and Ni foam (NF) as the current collector. Benefiting from the unique structure, the obtained 1-C3N4/Co3O4 hybrid nanosheets can significantly reduce the charge transfer distance between the catalysts to electron collector and improve the electron transportation during the OER process. Moreover, the intimate interaction of Co3O4 with C3N4 can induce a charge redistribution at the interface. Consequently, the 1-C3N4/Co3O4/NF hybrid electrode exhibits an enhanced OER performance (166 mV at 10 mA•cm−2) and good stability, superior to the commercial RuO2 particles and the reported transition metal-based electrocatalysts.

In the citing paper
“Ru4+ in Ru0.7Co0.3 aerogel is the major active center for OER, but the high valent Co species is another non-negligible active component, and the presence of oxygen vacancies raises the carrier level and promotes the OER process as well”

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.
