Oxygen evolution reaction (OER) is often considered as a major bottleneck in water splitting because of its slow kinetics and limited energy conversion efficiency. Herein, we constructed ZnO-Cu₂S nanoflower arrays on copper foam (CF) substrate with porous structure and high conductivity for accelerated mass transfer and electron transfer. The ZnO-Cu₂S heterostructure can generate a simple electron transport pathway, optimize the water adsorption energy, and thus improve the electrochemical performance. Meanwhile, superhydrophilic and aerophobic of ZnO-Cu₂S/CF is conducive to the immersion of electrolyte, and the bubbles can be quickly detached from the electrode surface. As a result, the current density of ZnO-Cu₂S/CF is 20 mA·cm⁻², the potential is only 1.359 V, and it is stable for 24 h. The improvement of OER performance of electrocatalyst is mainly due to the increase of active sites, the acceleration of electron transfer between electrode and electrolyte, and the synergistic effect between ZnO and Cu₂S. The design concept of ZnO-Cu₂S/CF with aerophobic heterostructures provides new ideas for the design and synthesis of future electrocatalysts.

析氧反应 (OER) 由于其缓慢的动力学和有限的能量转换效率，通常被认为是水分解的主要瓶颈。在此，我们在具有多孔结构和高导电性的铜泡沫 (CF) 基板上构建了 ZnO-Cu _{2 S 纳米花阵列，以加速传质和电子传递。}ZnO-Cu ₂ S异质结构可以产生简单的电子传输途径，优化水吸附能，从而提高电化学性能。同时，ZnO-Cu ₂ S/CF的超亲水疏气性有利于电解液的浸入，气泡可以快速脱离电极表面。因此，ZnO-Cu ₂ S/CF的电流密度为20 mA·cm^{-2 时}，电位仅为1.359 V，可稳定24 h。电催化剂OER性能的提升主要得益于活性位点的增加、电极与电解质之间电子转移的加速以及ZnO与Cu 2 _{S之间的协同作用。ZnO-Cu 2} S/CF的设计理念与疏氧异质结构为未来电催化剂的设计和合成提供了新的思路。
