【Ten Years of Rapid Development in Chemical Engineering Equipment】1287–2023: Tsinghua University develops a patented electrode that improves the efficiency of hydrogen production through water electrolysis

Thread Content

Tsinghua University has developed a patented electrode that can improve the efficiency of hydrogen production through water electrolysis. According to a notice issued by the **Intellectual Property Office, Tsinghua University filed an application for a catalyst electrode based on nickel and loaded with iron and ruthenium; the publication number is CN117165993A, and the application was submitted in August 2023. The patent abstract indicates that the present invention provides a nickel-based catalyst electrode loaded with iron and ruthenium, as well as its preparation method and applications. The nickel-based catalyst loaded with iron and ruthenium comprises a nickel mesh and at least one layer of layered structure deposited on the surface of the nickel mesh; said layered structure contains iron and ruthenium distributed in the form of nanoparticles. This catalyst can be applied to water electrolysis for hydrogen production; it exhibits high reactivity and stability in alkaline environments, enabling an improvement in the efficiency of hydrogen production via water electrolysis and facilitating large-scale production.
