PEM fuel cells are expected to play dominant role in future cle
 an energy solutions for various applications. Developing highly efficient 
 low-Pt and Pt-free catalysts are the key solutions for the wide-spread com
 mercialization of PEMFCs. We recently developed various novel Fe-based cat
 alysts which exhibited higher activity in alkaline media and equivalent ac
 tivity in acidic electrolyte compared to commercial Pt. [1] Moreover\, we 
 systematically studied the decay mechanism of the MOF-based Fe/N/C catalys
 t\, which is of significant important to improve the durability of Fe/N/C 
 catalysts [2\, 3]. On the other hand\, through green chemistry and/or ALD 
 techniques\, we fabricated various novel Pt nanostructures\, including nan
 owires\, nanotubes\, and single atoms. Compared to the conventional Pt nan
 oparticle/C commercial catalyst\, these novel Pt nanostructures exhibited 
 much enhanced activity (up to 10 times) and stability (up to 6 times) for 
 fuel cells [4-10].
Both lithium-ion (LIB) and sodium-ion batteries (SIB) a
 re promising technologies for energy storage. We developed a facile\, inex
 pensive and scalable wet-chemical strategy to fabricate the Fe3O4/graphene
  composites and porous carbon spheres. The nanocomposite shows dramaticall
 y enhanced electrochemical properties including excellent reversible capac
 ity\, cyclability and rate performance in LIBs and SIBs [10\,11].

Bio:
Prof. Shuhui Sun is currently working 
 at the Institut National de la Recherche Scientifique (INRS)\, center for 
 Energy\, Materials\, and Telecommunications\, Canada. His research interes
 ts focus on the development of multi-functional nanomaterials (graphene\, 
 CNTs\, MOF\, metal and metal oxides) for Energy and Environmental applicat
 ions\, including PEM fuel cells\, Li-ion and Na-ion batteries\, supercapac
 itors\, and Wastewater treatment. He has published 4 book chapters and ove
 r 70 peer reviewed articles in journals including Adv. Mater.\, Angew. Che
 m. Int. Ed.\, Adv. Energy Mater.\, Adv. Funct. Mater.\, Nano Energy\, with
  over 4\,000 citations (H-index = 31). He is listed as an inventor on 2 US
  patents (granted). He is the recipient of various awards\, such as Canada
  Governor General's Gold Medal Award (2012)\, ISE travel award (2010)\, Al
 exander Graham Bell Canada NSERC fellowship (2009). He is a member of Glob
 al Young Academy (GYA)\, ISE\, ECS\, CSC\, CQMF\, Plasma Quebec\, and UNES
 CO Chair for Materials and Technology for Energy Conversion\, Saving and S
 torage (MATECSS). Dr. Sun also serves as the editor of Nano Advances\, and
  the editorial board member for 6 journals.
