In this work, we synthesize P-doped Ir metallene (P-Ir metallene) with rich defects as a highly active bifunctional catalyst towards the hydrogen evolution reaction and oxygen evolution reaction, requiring overpotentials of 28 and 279 mV to drive 10 mA cm in 0.5 M HSO, respectively. Moreover, P-Ir metallene exhibits excellent electrocatalytic performance for overall water splitting, producing hydrogen at 10 mA cm with a low operation voltage of 1.508 V. This study proposes the incorporation of phosphorus into noble metals to improve the electrocatalytic performance for water splitting.
在这项工作中，我们合成了具有丰富缺陷的P掺杂铱金属烯（P-Ir金属烯），作为用于析氢反应和析氧反应的高活性双功能催化剂，在0.5 M H₂SO₄中驱动10 mA cm⁻²分别需要28和279 mV的过电位。此外，P-Ir金属烯在全水解中表现出优异的电催化性能，在1.508 V的低工作电压下以10 mA cm⁻²的电流产氢。本研究提出将磷掺入贵金属中以提高析水的电催化性能。
