Functionalized designs such as doping can effectively reduce charge transfer impedance and accelerate charge transfer dynamics. In this study, we reported a facile method to synthesize Ag-doped ZIF-67 hollow nanoboxes (Ag-CoP HNBs) by introducing Ag into cobalt-centered zeolitic imidazolate framework (ZIF-67). Its unique hollow structure results in higher stability, more active sites and bigger specific surface area with excellent HER and OER performance. Specifically, Ag-CoP HNBs requires only 97 and 256 mV to achieve a current density of 10 mA cm(-2) for HER and OER in 1.0 M KOH, respectively. Meanwhile, merely a voltage of 1.53 V is needed for delivering a current density of 10 mA cm(-2) for overall water splitting. Moreover, Ag-CoP HNBs exhibits excellent antibacterial activity for different bacteria due to the presence of Ag. In conclusion, this study provided a facile, feasible and productive way for developing Ag contained bifunctional electrocatalysts with antibacterial activity, which might have potential use in seawater splitting.
