Ultralow platinum-doped self-supported CoPt alloy nanosheets for efficient overall water splitting
In this study, CoPt alloy nanosheets (CoPt-R10) were <i>in situ</i> constructed on titanium mesh using electrodeposition and mild reduction methods. CoPt-R10 incorporates ultra-low amounts of Pt (0.42 at%) to modulate the electronic structure of Co, requiring low overpotentials of 210 and 314 mV to achieve 200 mA cm<sup>-2</sup> for HER and OER, respectively. CoPt-R10 serves as a bifunctional catalyst for overall water splitting, demonstrating stable operation for 500 hours at 100 mA cm<sup>-2</sup>.
