Germanane (GeH), a germanium analogue of graphane, has recently attracted considerable interest because its remarkable combination of properties makes it an extremely suitable candidate to be used as 2D material in (opto)electronic devices. Up to now, the synthesis of GeH has been conducted by substituting Ca by H in a <i>β</i>-CaGe<sub>2</sub> layered Zintl phase through topochemical deintercalation in aqueous HCl. This reaction is generally slow and takes place over 6 to 14 days. The new and facile protocol presented here allows to synthesize GeH at room temperature in a significantly shorter time (few minutes), which renders this method highly attractive for technological applications. In view of possible applications and to extend the use of GeH to unexplored fields, we investigated its antibacterial activity and found that this promising 2D structure exhibits remarkable antibacterial activity against both Gram-negative and Gram-positive bacterial strains.
