Research on the construction of sub-nanoscale Pd and Pt metal clusters to achieve efficient dehydrogenation of organic hydrogen molecules

Recently, the team of Liu Hongyang, a researcher at the Shenyang National Research Center for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, together with Professor Martin of Peking University, Professor Li Jun of Tsinghua University, Professor Wang Yanggang of Southern University of Science and Technology, Professor Zhou Wu of University of Chinese Academy of Sciences, and Professor Wang Ning of Hong Kong University of Science and Technology, etc.

Hydrogen has the advantages of high energy density, economical and environmental protection, but the storage and transportation of hydrogen is the bottleneck hindering the large-scale application of hydrogen energy

The research team precisely constructed isolated atomically dispersed platinum single atoms (Pt1), fully exposed platinum clusters (Ptn) of different sizes, and traditional platinum on the surface of defect-rich graphene-coated nano-diamond supports (ND@G) support.

Based on the above research work, the research team found that the sub-nanoscale fully exposed Pdn cluster catalytic material also showed excellent dehydrogenation and hydrogen production performance in the dodecahydrocarbazole dehydrogenation reaction

Liu Hongyang's research team used the design theory of sub-nanoscale metal catalytic materials to guide the production of practical industrial catalysts, and developed a low-content palladium-based catalyst for the hydrogenation of dinitrotoluene.

The research work has been supported by the key research and development plan of the Ministry of Science and Technology, the major research plan of the National Natural Science Foundation of China, the key project of the joint enterprise fund, the China-Hong Kong joint fund for international cooperation, the Liaoning Province Xingliao Talent Plan, the Chinese Academy of Sciences Institutional Research Project, the Chinese Postdoctoral Fund, etc.
