Metal–organic frameworks (MOFs) have emerged as promising catalysts for electrocatalytic applications. Their fascinating properties, such as high surface area, tunable metallocenters and functional groups, are highly notable. The incorporation of MOFs into the polymeric fibers is considered to be an important finding in various research fields. An electrospinning technique is considered to be the most reliable way to synthesize one-dimensional nanofibers. In this study, we have synthesized a bimetallic zeolite imidazolate framework (ZIF) material, and the synthesized material is incorporated with a suitable polymer for the formation of nanofibers. The polymeric property of the obtained CoNi-ZIF-RT has been tested by annealing at 500 °C in nitrogen (N₂) and air atmospheric conditions, which were assessed for electrocatalytic oxygen evolution reaction (OER) in 1 M KOH. Because of its high polymeric nature along with its virtuous intrinsic activity, CoNi-ZIF-RT had shown high electrocatalytic OER activity with facile electron transfer and extraordinary stability. CoNi-ZIF nanofibers have been synthesized via an electrospinning approach and are denoted as CoNi-ZIF-RT, CoNi-ZIF-500-N₂, and CoNi-ZIF-500-Air as per their synthesis procedure. Interestingly, CoNi-ZIF-RT showed better OER activity in an alkaline medium compared to the other materials.

包含CoNi基沸石咪唑酸酯骨架纳米粒子的聚合物纳米纤维用于电催化水氧化

金属有机骨架（MOF）已经成为电催化应用中有希望的催化剂。它们的引人入胜的特性（例如高表面积，可调整的金属中心和官能团）非常引人注目。在各种研究领域中，将MOF掺入聚合物纤维被认为是重要的发现。电纺丝技术被认为是合成一维纳米纤维的最可靠方法。在这项研究中，我们已经合成了一种双金属咪唑酸盐沸石骨架（ZIF）材料，并且将合成的材料与合适的聚合物结合在一起以形成纳米纤维。所得CoNi-ZIF-RT的聚合性能已通过在氮气（N ₂）和大气条件，对1 M KOH中的电催化氧释放反应（OER）进行了评估。由于其高聚合性和良好的内在活性，CoNi-ZIF-RT表现出高的电催化OER活性，并且电子转移方便且具有出色的稳定性。CoNi-ZIF纳米纤维已通过电纺丝方法合成，按照其合成程序表示为CoNi-ZIF-RT，CoNi-ZIF-500-N ₂和CoNi-ZIF-500-Air。有趣的是，与其他材料相比，CoNi-ZIF-RT在碱性介质中显示出更好的OER活性。
