The global temperature rise due to excessive greenhouse gas emissions has spurred research into renewable energy. Hydrogen, known for its high energy density and lack of carbon byproducts when converted to other energy forms, is gaining significant attention. Water electrolysis is a promising method for producing green hydrogen. It is divided into alkaline water electrolysis (AWE) and proton exchange membrane electrolysis (PEMWE). Recently, anion exchange membrane (AEM) electrolysis, combining the benefits of both, has been developed. This advancement allows for the use of non-platinum group metal (non-PGM) electrodes, although their performance still falls short of PEMWE. Thus, developing highly active catalysts is crucial. In this study, we synthesized a binder-free electrode by directly growing the catalyst on the electrode through a simple one-step process, achieving excellent performance in AEM electrolysis. |
