A research team led by Dr. Albert Sung Soo Lee at the Korea Institute of Science and Technology (KIST) has developed a groundbreaking catalyst design using molybdenum-based MXene as an electrocatalyst support for anion exchange membrane water electrolyzers. As countries worldwide commit to achieving 'net-zero' carbon emissions by 2050, hydrogen is gaining prominence as a clean energy source due to its emission of only water and oxygen when used. The study, in collaboration with Sungkyunkwan University, introduces an oxidatively stable MXene that can be utilized in green hydrogen production methods, offering a more eco-friendly approach to electrolyzing water using renewable energy. The article explains that the breakdown of water into hydrogen and oxygen requires significant energy, which can be reduced by using catalysts. MXenes, nanomaterials composed of metal atoms and carbon or nitrogen atoms, provide a conducive 2D nanostructure for catalyst support, making them ideal for hydrogen production. By using molybdenum-based MXene as a support, the research team established strong chemical bonds that significantly improved hydrogen production efficiency and durability, surpassing the performance of titanium-based MXenes. The advancement is crucial for lowering the cost of green hydrogen production and enabling its application in large-scale facilities. Dr. Albert Sung Soo Lee envisions a future where oxygen-generating electrode catalysts with enhanced efficiency and durability will drive the hydrogen-based economy forward. This research marks a significant step towards achieving cost-effective and sustainable green hydrogen production, contributing to global efforts in combating climate change.
