Prof. Haiyan Leng | Hydrogen Storage Materials | Best Researcher Award

Shanghai University | China

Prof. Haiyan Leng, a professor and doctoral supervisor at Shanghai University, specializes in lightweight hydrogen storage materials and high-capacity hydrogen storage device design. She has led and participated in multiple national and enterprise-funded projects, published over 70 SCI papers in top journals, and holds more than ten domestic and international patents. Her recent highly cited work in the Journal of Rare Earths investigates the influence of La and Ce rare earth doping on the hydrogen absorption properties of Zr7V5Fe alloy. The study revealed that rare earth doping enhances activation with shorter incubation periods and improves the transition of Zr and V from oxidized to metallic states during heating, leading to better hydrogen absorption performance. X-ray diffraction showed reduced cell volume of ZrV2 and α-Zr phases, raising plateau pressure, while kinetic analysis indicated coarser α-Zr phases and larger particle sizes, slightly reducing hydrogen absorption kinetics. Overall, the research provides valuable technical guidance for optimizing zirconium-based alloys for hydrogen storage applications.
