A research team from Xi’an Jiaotong University has overcome the problem of \"corrosion\" in hydrogen catalysts, enabling self-repair. Recently, Xi’an Jiaotong University made an important breakthrough in this field by discovering a new method that allows catalysts to repair themselves. A research team from Xi’an Jiaotong University has come up with a new approach that allows catalysts to repair themselves during use; it’s as if a \"renewal system\" is built into the catalysts, which continuously adjusts and restructures itself while in operation to maintain optimal performance. Zhao Xu, a researcher at the School of Chemical Engineering at Xi’an Jiaotong University: Through the structural design of our catalyst, it is possible to create a highly stable and high-performance catalyst structure under these operating conditions, thereby enabling long-term and reliable electrolytic water splitting for hydrogen production. The traditional approach to catalyst design, which involves determining their properties at the time of production, aims to ensure that they maintain their perfect state from that point onward. Zhao Xu’s team adopted a different approach – since the structure of the catalyst was bound to change, they decided to take advantage of this change and steer it in a positive direction, turning what was uncontrolled into something controllable. Experimental data show that, using the catalyst they developed, only 3.9 kWh of electricity is required to produce one standard cubic meter of hydrogen in an anion-exchange membrane electrolyzer.
