Black phosphorus (BP) has attracted a lot of interest in the fields of oxygen evolution reaction (OER). Nevertheless, in terms of single use of BP as a catalyst, the inherent instability and poor conductivity of BP often limit further improvement of OER catalytic performance. Herein, we report a method using mechanical shear force to fully mix the carbon nanotubes (CNTs) and red phosphorus powder (RP) to obtain a hybrid dimensional (RP-BP/CNTs) heterostructured metal-free electrocatalyst with excellent OER performance in alkaline media. During the ball milling process, some RP is transformed into BP due to shear stress and high-temperature in-situ phase transformation. Meantime, a large number of defects in CNTs cut by ball milling combine with the lone pair of BP to form a P–C bond, resulting in a heterojunction structure. By rational interface engineering, the hybridisation of RP-BP and CNTs improves the electroconductivity and has excellent durability. The results demonstrate that RP-BP/CNTs heterostructure shows good OER performance with a low overpotential of 263 mV vs. RHE at a current density of 10 mA cm⁻², lower than that of commercial RuO₂ (310 mV vs. RHE, 10 mA cm⁻²). The small Tafel slope indicates that the catalyst has higher catalytic performance, while the stable structure ensures its long-term durability.

黑磷（BP）在制氧反应（OER）领域引起了很多兴趣。然而，就单独使用BP作为催化剂而言，BP固有的不稳定性和差的电导率通​​常会限制OER催化性能的进一步提高。本文中，我们报道了一种使用机械剪切力将碳纳米管（CNT）和红磷粉末（RP）充分混合以获得在碱性介质中具有优异OER性能的杂化尺寸（RP-BP / CNTs）杂化结构的无金属电催化剂的方法。 。在球磨过程中，由于剪切应力和高温原位相变，一些RP转变为BP。同时，通过球磨切割的CNT中的大量缺陷与孤立的BP对结合形成P–C键，从而形成异质结结构。通过合理的界面工程，RP-BP和CNT的杂化提高了导电性并具有出色的耐久性。结果表明，在电流密度为10 mA cm时，RP-BP / CNTs异质结构具有良好的OER性能，与RHE相比具有263 mV的低过电势^－2低于商业RuO _2的（－310 mV对RHE，10 mA cm ^-2）。塔菲尔斜率小表明该催化剂具有较高的催化性能，而稳定的结构可确保其长期耐久性。
