Biography
John Wang is Professor of Materials Science and Engineering at the National University of Singapore (NUS).
Prof. John Wang has more than 30 years of experience in research and education of functional materials and materials chemistry, after obtaining his PhD from the University of Leeds (1987).
Prof. John Wang has published >400 papers in prestigious, top international refereed journals, with H-index of 84.
Professor John Wang is elected Academician of the Asia Pacific Academy of Materials (APAM).
Professor Wang’s research focuses on new functional ceramics, electroceramic and composite materials that are inevitably required for the next generation of energy generation and storage, electronics and healthcare. His research group has been working on novel fabrication techniques for these materials and understanding of the correlations between their structural parameters, at various length scales ranging from molecular, nanometer to micrometer ranges, and their functional properties.
More recently, Professor Wang’s research is concentrating on carbon-based materials, nanohybrids and mesoporous materials for energy generation, energy storage and biomedical applications. He and his research group have successfully developed several types of new nanohybrids and mesoporous materials for applications in energy generation storage and drug delivery.
Abstract
There has been an intensive search for heterogeneous single atom catalysts (SACs) of high activity, efficiency, durability and selectivity for a wide variety of electrocatalytic energy conversion and chemical reactions, in recent years.
With the down-sizing from nanoparticles, nanoclusters and now to single atoms, and the steady switching from noble metals to transition metals, there are steady changes in the bond and coordination environment for each and every atom involved.
These single atoms are not “singles” anymore; they are actually “married” to the supporting surfaces, and their performance is largely controlled by the “marriage” with the substrate surfaces, instead of themselves.
In this talk, we will present our latest advances in search for better heterogeneous single atom electrocatalysts, by focusing on their rational design, synthesis, control in composition, and strategies to realize the single atoms with the most desired bonds and coordination for targeted performance, where catalytic activity, selectivity and long-term stability are among the key parameters.
Examples are those targeted for applications in the energy storage and conversion targeted for portable and flexible devices, and those for environments.
