A research team at the Korea Institute of Science and Technology (KIST), in collaboration with Sungkyunkwan University, has made significant strides in green hydrogen production by developing an oxidatively stable MXene-based catalyst for anion exchange membrane water electrolyzers. This innovative catalyst, detailed in the journal Applied Catalysis B: Environment and Energy, utilizes molybdenum-based MXene as a support, enhancing hydrogen production efficiency. With 137 nations committing to net-zero carbon emissions by 2050, hydrogen is gaining prominence as a clean energy source due to its emission-free energy conversion process. The study highlights the three hydrogen production methods: gray, blue, and green, with green hydrogen produced through water electrolysis using green energy being the most environmentally friendly. The research team's focus on creating a durable catalyst support addresses the inefficiencies caused by catalyst degradation over time, ultimately aiming to reduce the costs of large-scale green hydrogen production. By forming strong chemical bonds between molybdenum-based MXene and cobalt, the catalyst significantly improved hydrogen production efficiency. The team's work not only enhances the durability of the catalyst but also contributes to the advancement of green hydrogen technologies for a sustainable future. The findings open doors for the implementation of this innovative catalyst in future large-scale hydrogen production facilities and green hydrogen power stations, driving the global transition towards clean energy solutions.
