ScienceTechyNews: Uncovering the superconducting phosphine: P2H4 and P4H6

Phosphine (PH3), a typical hydrogen-rich hydride, has attracted a great deal of research interest because of its superconducting transition at high pressure. However,PH3 phase under compression has remained unknown and no relevant experimental studies have been reported. In a recent paper published in National Science Review, it reports the stoichiometric evolutions of PH3 under high pressure. The results suggest that the generated P4H6 might be responsible for the reported superconducting transition.
