Engineering an electrocatalytic anode material to boost reaction kinetics is highly desirable for the anodic oxygen evolution reaction (OER), which is the major obstacle for high efficiency water electrolysis. Here, we present a novel kind of Zn-doped Co₃O₄ hollow dodecahedral electrocatalyst. Abundant oxygen vacancy defects are introduced due to the incorporation of Zn²⁺, which is beneficial for OH⁻ adsorption and the charge transfer reaction during the OER process. Moreover, the increase in surface area caused by the advanced structure of the hollow porous dodecahedra facilitates mass transport by increasing the surface area. The novel strategy proposed in this study provides an efficient way to design high-performance electrocatalysts for water electrolysis.

对于阳极氧放出反应（OER），非常需要设计一种能提高反应动力学的电催化阳极材料，这是高效水电解的主要障碍。在这里，我们提出一种新型的Zn掺杂的Co ₃ O ₄空心十二面体电催化剂。丰富的氧空位缺陷被引入由于锌的掺入²⁺，这是有益的OH ^-OER过程中的吸附和电荷转移反应。此外，由中空多孔十二面体的先进结构引起的表面积的增加通过增加表面积而促进了质量传输。在这项研究中提出的新策略提供了一种有效的方法来设计用于水电解的高性能电催化剂。
