With a diameter of only 1.3 nm, the utilization rate is as high as 48.6%. The reporter learned from the China University of Science and Technology (abbreviated as China University of Science and Technology) on the 5th that researchers from the school developed a platinum nanowire catalyst. According to researcher Huang Hongwen, the use of this catalyst in batteries allows the battery to have high energy conversion efficiency and low pollution emission characteristics. Prof. Zeng Jie of the University of Science and Technology of China, Prof. Peng Zhenmeng from the University of Akron in the United States, and Prof. Shi Rui of the Shanghai Institute of Applied Physics, Chinese Academy of Sciences, made significant progress in the development of cathode catalysts for proton exchange membrane fuel cells, and designed a platinum ultrafine nanowire catalyst. . The results show that the mass activity and specific activity of this novel catalyst are 7.8 times and 5.4 times higher than those of commercial platinum carbon catalysts, respectively. The results were recently published in the Journal of the American Chemical Society. Current published data shows that although platinum-based catalysts have excellent mass activity, their stability is often not impressive. In response to this problem, the researchers designed and synthesized a ruthenium-doped platinum ultrafine nanowire catalyst with the help of atomic-level fine synthesis technology. Its diameter is only 1.3 nm, and the utilization of platinum atoms is as high as 48.6%. . The results showed that the catalyst lost only 9.2% of mass activity after being recycled for 10,000 times in an oxygen atmosphere. It is reported that the current commercial platinum carbon catalyst under this condition, the loss of mass activity performance reached 72.3%. According to reports, this type of catalyst performs “good†in the cathode oxygen reduction reaction of fuel cells, which can significantly save the amount of precious metal platinum, which is of positive significance in promoting the commercialization of clean energy conversion technology.
