报告摘要:

H2/O2 fuel cells hold very promising potential in future mobile and stationary applications due to their high energy efficiency, high power density, as well as low/zero emissions. Currently, Pt-based catalysts are usually used as the electrocatalysts in H2/O2 fuel cells, however, their limited availability and high cost (contribute over 50% of the total fuel cell cost) hinder the wide commercialization of this technology. We are working on two different approaches to solve this challenge: (i) the first strategy is to use nanotechnology

to significantly increase the activity and durability of Pt-based catalysts through morphology and size control. We have developed several advanced techniques, such as green chemistry and atomic layer deposition (ALD), to fabricate a series of novel nanostructured Pt catalysts, such as nanowires (NWs), nanotubes (NTs), sub-nanoclusters, single atoms, etc. All these new types of catalysts exhibit much enhanced activity (up to 10 times) and stability (up to 6 times) compared to the commercially-used Pt/C nanoparticle catalysts. (ii) The second strategy is to develop very cheap non-precious-metal-based electrocatalyst materials.

Prof. Shuhui Sun joined INRS-EMT in 2012 (http://www.inrs.ca/english/about-us/overview-inrs).His current research interests focus on the development of multi-functional nanomaterials for energy conversion and storage, and environmental applications. His major expertise areas are the controlled synthesis of various nanomaterials, including graphene, doped-graphene, carbon nanotubes, metal and metal oxide nanostructures, and nanocomposites, as well as their applications in H2/O2 fuel cells, methanol fuel cells, formic acid fuel cells, supercapacitors, Li-ion battery, and waste water treatment. He has published over 60 peer-reviewed scientific papers (e.g., Angew, Chem. Int. Ed., Advanced Materials, Chemistry Materials, Scientific Reports,…), 3 book chapters, and has delivered over 30 invited talks/seminars, and hold 2 US patents. His entire publications have been cited for over 2500 times with an H-index of 28. He has received a series of prestigious academic awards, such as the 1st Prize of Natural Science Award of Anhui Province, Quebec Merit Fellowship, Alexander Graham Bell Canada Fellowship, ISE Travel Award for Young Electrochemists, Canada Governor General's Gold Medal, and Canada Foundation for Innovation-Leaders Opportunity Fund Award. He is the member of ISE, ECS, CSC, CQMF, Plasma Quebec, UNESCO Chair on MATECSS, and Full Member of the Sigma Xi Society. He is the Guest editor of Electrochimica Acta, International Journal of Hydrogen Energy, and Applied Energy, the Review editor of Frontiers in Energy Storage, and the Editor board member of Journal of Nanotechnology, and ISRN Nanomaterials, the Vice President of the Publication Division of The International Academy of Electrochemical Energy Science (IAOEES).
