Abstract

Bismuth halide perovskites have emerged as promising alternatives for sustainable and efficient photocatalysts for light-induced organic transformations. Caesium bismuth halide perovskites (Cs3Bi2(ClxBr1-x)9) with different ratios of chloride and bromide were synthesised using a one-step solution process. These perovskites were then employed as photocatalysts for the photocatalytic oxidative coupling of benzylamine (BZA) to produce N-benzylidenebenzylamine (BZI) under ultraviolet-visible light radiation at ambient conditions. The incorporation of bromide ions into the chloride-based perovskite resulted in a noticeable reduction in the bandgap, leading to an enhancement in the photocatalytic activity. Conversely, the addition of chloride ions within the bromide-based perovskite was found to be beneficial for the material's photostability while simultaneously maintaining its high photocatalytic activity. The optimal compromise between the stability and photocatalytic activity for the BZI production was achieved using Cs3Bi2(Cl0.8Br0.2)9, being attained a total BZA conversion and the maximum BZI production with 100 % of selectivity after 6 hours of irradiation. The efficiency of this photocatalyst was ascribed to the highest current density observed during the photocurrent experiments, which improves the charge carrier mobility of the resulting material. Caesium bismuth halide perovskites with different ratios of chloride and bromide are synthesized through a one-step solution process. These perovskites demonstrated enhanced photocatalytic activity in the oxidative coupling of benzylamine toN-benzylidenebenzylamine under ultraviolet-visible light. Incorporating bromide ions improved photocatalytic efficiency, while adding chloride ions enhanced material photostability, achieving the best performance in Cs3Bi2(Cl0.8Br0.2)9. image

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 2026-04-02:

  • 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: 6.
  • 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: 6 (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 X (formerly Twitter): 1 (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.
