The sustainable energy technology is in great demand due to the depletion and the risks associated with the use of fossil fuels. Various energy technologies like regenerative fuel cells, zinc-air batteries, and overall water-splitting devices have a huge scope in the growth of green energy. The efficiency of these devices is reliant upon the multifunctional electrocatalysts, which include both bifunctional and trifunctional electrocatalysts. Among the different categories of the materials used for such multifunctional electrocatalysis, metal-organic-frameworks (MOFs) occupy a very consolidated place because of their high surface area, porosity, and many other unique physicochemical properties. However, the use of MOFs for the trifunctional electrocatalytic applications is in the budding phase and needs to be explored more. Further, most of these MOF-based trifunctional electrocatalysts are derived by pyrolyzing MOFs at high temperatures. Therefore, there is a need to develop more conductive MOFs which can be directly utilized for the trifunctional applications. In this frontier article, we present the latest reports on the MOF-based materials for trifunctional applications. The material design strategies of the MOF-based materials for trifunctional electrocatalysis have been discussed. The progressive improvements made with MOFs in electrocatalytic applications have been provided with emphasis on the structural, active site and compositional requirements. Finally, the challenges and viewpoints on the future development of the MOF-based materials for trifunctional electrocatalysis have been provided.
由于化石燃料的枯竭以及与使用化石燃料相关的风险，可持续能源技术的需求巨大。各种能源技术，如再生燃料电池、锌空气电池和全水分解装置，在绿色能源的发展中具有巨大的潜力。这些装置的效率依赖于多功能电催化剂，其中包括双功能和三功能电催化剂。在用于这种多功能电催化的不同材料类别中，金属有机框架（MOF）因其高表面积、孔隙率和许多其他独特的物理化学性质而占据非常稳固的地位。然而，MOF在三功能电催化应用中的使用尚处于萌芽阶段，需要更多地进行探索。此外，大多数这些基于MOF的三功能电催化剂是通过在高温下热解MOF得到的。因此，需要开发更多可直接用于三功能应用的导电MOF。在这篇前沿文章中，我们展示了关于用于三功能应用的基于MOF的材料的最新报告。讨论了基于MOF的材料用于三功能电催化的材料设计策略。强调了MOF在电催化应用中的逐步改进，包括结构、活性位点和组成要求。最后，提供了关于基于MOF的材料用于三功能电催化未来发展的挑战和观点。
