Abstract

Bimetallic CuFe nanoparticles covered by thin carbon layers were developed as a potential substitute for noble metal catalysts and have been used for chemoselective hydrogenation of 5-(hydroxymethyl)furfural (HMF) to 2,5-bis(hydroxymethyl)furan (BHMF). Compared to Cu catalysts supported on conventional solid carriers prepared by impregnation, the CuFe@C nanoparticles are active and more stable catalysts. The spatial distribution of the immiscible Cu and Fe in the bimetallic CuFe@C nanoparticles is dependent on the Cu/Fe ratio, and moreover, an optimized Cu/Fe ratio has been found for hydrogenation of HMF. In the fresh Fe@C and CuFe@C catalysts, their surfaces are passivated and covered by FeOx, due to oxidation by air. Based on detailed structural characterization and catalytic studies, small Cu nanoparticles supported on Fe nanoparticles are proposed to be the key active sites for hydrogenation of HMF. These Cu nanoparticles can not only serve as the active sites for hydrogenation of HMF but also promote the reduction of FeOx into metallic Fe, resulting in an increased number of active sites in the bimetallic CuFe@C catalyst compared to the monometallic Cu@C and Fe@C samples, resulting in significant promotion of the catalytic activity.

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 2026-04-06:

  • 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: 27.
  • 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: 27 (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: 2.
  • 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:
