my country has developed a proton exchange membrane fuel cell cathode catalyst
It was learned from the official website of the University of Science and Technology of China that recently, the research group of Professor Zeng Jie of the Hefei National Research Center for Microscale Physical Sciences of the University of Science and Technology of China and the School of Chemistry and Materials Science collaborated with Professor Huang Hongwen of Hunan University to finely control the dimensions, size, and size of platinum-based catalysts. Components, an ultrafine platinum-nickel-rhodium ternary metal nanowire catalyst was developed.
It is understood that the diameter of the nanowire is only one nanometer, and the ratio of platinum atoms on its surface to the total platinum atoms is higher than 50%, showing ultra-high atomic utilization and providing a structural basis for high catalytic mass activity.
In addition, oxygen reduction catalytic tests show that the mass activity of the carbon-supported ultrafine platinum-nickel-rhodium ternary metal nanowire catalyst is 15.2 times that of the current commercial platinum-carbon nanocatalyst. At the same time, the carbon-supported ultrafine platinum-nickel-rhodium ternary metal nanowire catalyst only lost 12.8% of its mass activity performance after being recycled 10,000 times in an oxygen atmosphere. In contrast, the commercial pt/C catalyst After 10,000 cycles in an oxygen atmosphere, the mass activity loss reached 73.7%.
According to reports, this is a proton exchange membrane fuel cell cathode catalyst with excellent catalytic activity and stability.
Technology Zone Zimi announced that the 27W version of the 20000mAh Aura two-way fast charging digital display mobile power supply will go on sale on December 5. my country has developed a proton exchange membrane fuel cell cathode catalyst. Indonesia will build the world's largest lithium battery factory. The project plans to invest US$4 billion in 2019. How high the energy density can power batteries achieve? Foreign countries used ultramicroscopes to observe the electrochemical charge and discharge process of lithium ions.
