The search for an inexpensive bifunctional electrocatalyst for overall water splitting has attracted considerable research interest during the past years. Herein, self‐supported hierarchical electrodes comprising nickel foam (NF) and porous molybdenum phosphide (MoP) nanoflakes are fabricated by first growing MoO₂ nanoflakes on Ni foam and then further phosphorization treatment. Remarkably, serving as both anode and cathode catalysts in a two‐electrode alkaline water‐electrolysis system, the designed electrodes only require a potential of 1.62 V to deliver a current density of 10 mA cm⁻². This performance is close to that of the noble‐metal‐based electrodes, that is, integrated RuO₂/Ni foam and Ni foam supported Pt/C electrodes. The low cost, facile preparation method, and desirable performance make this MoP/NF electrode a potential electrocatalyst for overall water splitting.

Ni泡沫支撑的MoP纳米片状分层阵列：一种用于整体水分解的双功能电催化剂

在过去几年中，寻求用于整体水分解的廉价双功能电催化剂引起了相当大的研究兴趣。在本文中，首先通过在Ni泡沫上生长MoO ₂纳米薄片，然后进行进一步的磷化处理，来制造包含镍泡沫（NF）和多孔磷化钼（MoP）纳米薄片的自支撑分层电极。值得注意的是，设计的电极在双电极碱性水电解系统中既充当阳极催化剂，又充当阴极催化剂，仅需1.62 V的电势即可提供10 mA cm ^-2的电流密度。该性能接近贵金属电极，即集成的RuO ₂/ Ni泡沫和Ni泡沫支撑的Pt / C电极。低成本，简便的制备方法和令人满意的性能使该MoP / NF电极成为用于整体水分解的潜在电催化剂。
