Abstract

For carbon -free electrochemical fuel formation, the electrochemical cell must be powered by renewable energy. Obtaining solar -powered H2 fuel from water typically requires multiple photovoltaic cells and/or junctions to drive the water splitting reaction. Because of the lower thermodynamic requirements to oxidize ammonia compared to water, solar cells with smaller open circuit voltages can provide the required potential for ammonia splitting. In this work, a single perovskite solar cell with an open -circuit potential of 1.08 V is coupled to a 2 -electrode electrochemical cell employing hybrid electroanodes functionalized with Ru-based molecular catalysts. The device is active for more than 30 min, producing N2 and H2 in a 1:2.9 ratio with 89% faradaic efficiency with no external applied bias. This work illustrates that hydrogen production from ammonia can be driven by conventional semiconductors. (c) 2024 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences.

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 2025-09-08:

  • 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: 9.
  • 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: 9 (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: 1.5.
  • The number of mentions on the social network X (formerly Twitter): 3 (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:
