In a global effort to combat climate change, 137 countries have pledged to achieve net-zero carbon emissions by 2050, highlighting hydrogen as a key green energy source. Green hydrogen production, in particular, is recognized as the most environmentally friendly method, utilizing electrolysis with green energy to generate hydrogen without carbon emissions. A research team at the Korea Institute of Science and Technology (KIST) has made significant strides in this area by developing an oxidatively stable molybdenum-based MXene as an electrocatalyst support for anion exchange membrane water electrolyzers. This advancement aims to reduce the cost of green hydrogen production by enhancing efficiency and durability. By utilizing MXene as a support material, the team established strong chemical bonds between molybdenum atoms and active materials, leading to a substantial increase in hydrogen production efficiency and unit cell durability. The research, supported by the Korean government, marks a pivotal step towards realizing the potential of green hydrogen for large-scale applications in the future. Dr. Albert Sung Soo Lee emphasized the importance of developing efficient and durable catalysts for oxygen generation, laying the foundation for a hydrogen-driven economy. The study, published in Applied Catalysis B: Environment and Energy, underscores the crucial role of innovative materials and collaborative research in advancing sustainable energy solutions.
