Common pathogenic bacteria contaminate the environment through various modes of transmission. It is thus crucial to develop simple preparation methods of residue-free environmental disinfectants. β-Lactam antibiotics are frequently prescribed in clinical practice to treat bacterial infections. In this study, we used electrochemical exfoliation to synthesize graphene oxide (GO) with abundant ketene functional groups. A residue-free GO-β-lactam (GOβL) was subsequently obtained by mixing ketene and azomethine-H via a [2 + 2] cycloaddition reaction in the aqueous phase. GOβL has shown broad-spectrum bacterial inhibition against four bacteria (, , , and ), and it degrades rapidly within 24 h. This study provides a fast and easy method for the synthesis of GOβL, which can be employed as a promising environmental bacteriostatic disinfectant in real-life applications.
