Abstract

A heterogeneous ruthenium catalyst consisting ofisolated single atoms and disordered clusters stabilized in a N-doped carbon matrix has been synthesized with very good activityand remarkable regioselectivity in the hydroformylation of 1-hexene. The role of the nitrogen heteroatoms has been probedessential to increase the catalyst stability and activity, enabling thestabilization of Ru(II)-N sites according to X-ray photoelectronspectroscopy (XPS) and XANES. Intrinsic size-dependent activityof Ru species of different atomicity has been extracted, correlatingthe observed reaction rate and the particle size distributiondetermined by means of aberration-corrected high-angle annulardark-field scanning transmission electron microscopy, permittingthe identification of single-atom sites as the most active ones. This catalyst appears as a promising alternative with respect to itsheterogeneous counterparts, paving the way for designing improved Ru heterogeneous catalysts

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Acs Catalysis due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2022, it was in position 22/161, thus managing to position itself as a Q1 (Primer Cuartil), in the category Chemistry, Physical.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 2.2. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 2.18 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 6.98 (source consulted: Dimensions Jun 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-06-20, the following number of citations:

  • WoS: 37
  • Scopus: 39
  • OpenCitations: 30

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 2025-06-20:

  • 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: 35.
  • 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: 35 (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: 2.35.
  • The number of mentions on the social network X (formerly Twitter): 5 (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:
