It was learned from the University of Science and Technology of China on the 11th that the team of Professor Zeng Jie of the school and the team of Professor Jun Bao from the National Synchrotron Radiation Laboratory have developed a new type of hydrogen-oxygen fuel cell cathode catalyst
The catalyst has a hypercube frame structure and exhibits high activity and high stability in the cathode reaction of a hydrogen-oxygen fuel cell, which provides a new idea for the design of related electrocatalysts in the future
A fuel cell is a chemical battery that uses the energy released when a substance undergoes a chemical reaction to directly convert it into electrical energy
Inspired by the evolution of three-dimensional cubes to four-dimensional hypercubes, the Chinese University of Science and Technology team oxidized and etched the palladium-platinum uniform alloy cubes, and obtained the palladium-platinum alloy hypercube frame structure by precisely controlling the removal of palladium atoms and the rearrangement of the remaining palladium atoms and platinum atoms
In the battery cathode catalysis test, the unit mass activity of the cubic frame structure, the hypercube structure and the octapod structure reached 4.
