Tianjin University Researchers Unveil New Catalyst Synthesis Technology
TIANJIN, China – A research team from Tianjin University has published new findings in the journal Science detailing a millisecond-thermal-pulse technology for the ultra-fast synthesis and precise control of platinum group catalysts. The developed method aims to improve the performance of hydrogen fuel cells and advance green energy technologies.
The study introduces a "transient assembly" strategy for preparing core-shell structures of platinum group metals. These catalysts are critical for modern energy, chemical, and environmental industries, with precise construction of such structures key to high catalytic activity and reduced precious metal usage. The new method reportedly compresses a multi-step process that traditionally takes hours into mere minutes.
Furthermore, the technology facilitates the formation of a precisely controlled, three-atom-thick platinum layer, optimizing geometric and electronic effects to enhance catalytic activity. Energy consumption for catalyst synthesis is reduced by 90 percent per mass unit compared to conventional methods. The process also avoids the use of hazardous or highly polluting reagents.
Catalysts synthesized using the new method achieved a rated power of 15.2 kilowatts per gram of platinum in hydrogen fuel cells and demonstrated excellent durability. The technology is expected to support broader applications in green hydrogen, high-end chemical manufacturing, environmental catalysis, fine chemicals, and pharmaceutical synthesis.
