137 countries globally have signed an agreement aimed at achieving zero carbon emissions by 2050, promoting hydrogen as a sustainable energy source. A research team led by Dr. Albert Sung Soo Lee at KIST has developed an oxidatively stable molybdenum-based MXene as an electrocatalyst support for green hydrogen production. By utilizing this new catalyst, the efficiency of hydrogen production was increased by 2.45 times compared to traditional catalysts, with durability improved by over 10 times. This breakthrough is significant as it can potentially reduce the cost of green hydrogen production and enable the implementation of large-scale hydrogen production facilities. The study focused on using MXene nanomaterials due to their high electrical conductivity and suitable 2D nanostructure for catalyst support. By incorporating molybdenum-based MXene, the team was able to establish strong chemical bonds between the supporting material and the active catalyst, improving overall efficiency. This development addresses the challenge of maintaining high electrical conductivity in catalysts, which is crucial for sustainable hydrogen production. Dr. Albert Sung Soo Lee expressed optimism about the future application of this technology, stating that by fine-tuning the elements of MXene, stable support materials can be tailored for green hydrogen production environments. The research aims to contribute to the growth of a hydrogen-based economy by developing efficient and durable oxygen-generating electrode catalysts. This study marks a significant step towards revolutionizing green hydrogen production and advancing the transition towards a sustainable energy future.
