摘要

在本研究中，采用电沉积和轻度还原的方法在钛网上原位构建了CoPt合金纳米片（CoPt- r10）。CoPt-R10加入了超低量的Pt （0.42 at%）来调制Co的电子结构，分别需要210和314 mV的低过电位来实现200 mA cm-2的HER和OER。CoPt-R10作为双功能催化剂，在100毫安厘米-2下稳定运行500小时。

Ultralow platinum-doped self-supported CoPt alloy nanosheets for efficient overall water splitting†

In this study, CoPt alloy nanosheets (CoPt-R10) were in situ 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⁻² 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⁻².
