A recent study published by Professor Changzheng Wu's group at the University of Science and Technology of China has introduced a groundbreaking approach to revolutionize the synthesis of platinum-based intermetallic compounds for fuel cell electrocatalysis. By incorporating semimetal atoms such as Ge, Sb, and Te into the synthesis process, the traditional high-temperature requirement of around 600°C has been significantly lowered to just 300°C. This breakthrough allows for the creation of semimetal-platinum intermetallic compounds with enhanced properties. The key innovation lies in the formation of chemical bonds between semimetal elements and platinum atoms (Pt-Ge, Pt-Sb, Pt-Te), which possess characteristics of both metallic and covalent bonds. This unique bond structure not only overcomes the limitations of high-temperature synthesis but also improves the electrocatalytic performance of proton exchange membrane fuel cells. Furthermore, the study demonstrates that by leveraging the partial filling of p orbitals in the semimetal elements, a strong covalent interaction is established between platinum and semimetals. This interaction drives the ordering arrangement during the synthesis process, breaking the temperature constraints and promoting electron transfer in fuel cells. The newly developed semimetal-platinum intermetallic compounds exhibit exceptional oxygen reduction activity and anti-toxic ability in fuel cell electrochemical tests, surpassing commercial Pt/C catalysts by a significant margin. The study showcases the enormous potential of semimetal-induced covalency in optimizing fuel cell catalyst synthesis and performance. Overall, this research marks a significant step towards the rational design of advanced electrocatalysts for fuel cells, offering promising prospects for the future of hydrogen energy conversion and utilization.
