Abstract

The performance of OER anodes based on supported nanocatalysts is highly dependent on the interactions taking place at the interface between the nanocatalyst and the employed conductive support. Herein, the versatility offered by the organometallic approach for the synthesis of metal-based nanostructures allowed preparing electrodes of tailored nanocatalyst-support interactions. A set of OER working electrodes based on CoOH)(2) nanoparticles (NPs) and carbon microfibers (CFs) were prepared. The so-obtained systems differ in either the stabilizer present at the surface of the NPs (THF or 1-heptanol), the surface functionalization of the used CFs (bare CFs or oxidized-CFs) or the growth of the NPs in the presence (in situ) or the absence (ex situ) of the carbonaceous support. Correlation of a detailed structural and compositional analysis with the electroactivity of the tested nanomaterials allows extracting valuable insights about the influence of the metal-support interface on the OER performance of the studied anodes.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-08-02:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 24.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 24 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network Facebook: 1 (Altmetric).
  • The number of mentions on the social network X (formerly Twitter): 2 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
