·采用两步静态沉淀法在室温下制备了性能优良的ZIF@Ni-B-Co催化剂。· ZIF-67作为前体有利于增加ZIF@Ni-B-Co催化剂的比表面积，这有利于在OER期间暴露活性位点和电子转移。·在ZIF@Ni-B-Co中Ni-B-Co纳米颗粒和ZIF-67载体之间的共催化作用协同地增强OER性能。开发高效且地球资源丰富的非贵金属电催化剂用于析氧反应（OER）对于能量转换和存储基础设施至关重要。在此，我们通过一种简单的方法，没有任何能量损失，合成了一种钴基沸石咪唑骨架衍生的三硼化物电催化剂，命名为ZIF@Ni-B-Co，其具有优异的OER活性和稳定性。在10 mA cm −2的电流密度下，它具有300 mV的低过电位和77 mV dec −1的塔菲尔斜率，优于贵金属RuO 2。ZIF@Ni-B-Co催化剂的上级OER性能主要归因于金属-硼键的形成、特定的十二面体形貌、大的比表面积和快速的电荷转移速率。这一工作将为金属-有机骨架衍生复合材料的设计和制备提供新的线索，并为结晶工程的构建提供一些见解。
• The excellent ZIF@Ni-B-Co catalyst was prepared via two-step static precipitation method at room temperature without any energy loss. • ZIF-67 as a precursor is beneficial to increase the specific surface area of the ZIF@Ni-B-Co catalyst, which facilitates exposure of active sites and electron transfer during OER. • The co-catalytic effect between Ni-B-Co nanoparticles and ZIF-67 support in ZIF@Ni-B-Co synergistically enhances OER performance. Exploiting efficient and earth-abundant non-noble metal electrocatalysts for oxygen evolution reaction (OER) is extremely important for energy conversion and storage infrastructure. Herein, we synthesized a Co-based zeolite imidazolate framework-derived bimetallic boride electrocatalyst by a facile method without any energy loss, named ZIF@Ni-B-Co, which exhibits excellent OER activity and stability. At the current density of 10 mA cm −2 , it has a low overpotential of 300 mV and a Tafel slope of 77 mV dec −1 , which is better than noble metal RuO 2 . The superior OER performance is attributed to the formation of a metal-boron bond, the morphology of specific dodecahedron, the large surface area and the fast charge transfer rate for the ZIF@Ni-B-Co catalyst. This work will provide new clues for the design and fabrication of metal-organic framework-derived composites, and offer some insights into the construction of crystallinity engineering.
