arising from S. Kashiwaya et al. Nature Synthesis https://doi.org/10.1038/s44160-024-00518-4 (2024)

A facile and scalable synthesis process of atomic monolayer two-dimensional (2D) transition metals is of substantial interest to the materials research community, which is searching for new materials for semiconductor and catalyst applications. In their work, Kashiwaya et al.1 describe a process in which they claim to have synthesized goldene2, a freestanding, 2D single-atomic layer of gold. We argue that their claim of having synthesized 2D sheets of ‘goldene comprising single-atom layer gold’ is not substantiated by their experimental results. Therefore, in our opinion, this necessitates a re-evaluation of their manuscript.
