报告摘要：

PEM fuel cells are expected to play dominant role in future clean energy solutions for various applications since they can generate electricity without pollution. Developing highly efficient low-Pt and Pt-free catalysts are the key solutions for the wide-spread commercialization of PEM fuel cells. Through green chemistry and atomic layer deposition (ALD) techniques, we fabricated various novel Pt nanostructures, including nanowires, nanotubes, and single atoms. Compared to the conventional Pt nanoparticle/C commercial catalyst, these novel Pt nanostructures exhibited much enhanced activity (up to 10 times) and stability (up to 6 times) for fuel cells. On the other hand, we developed much cheaper Fe-based non-noble metal (e.g., Fe/N/C) catalysts which exhibited higher activity in alkaline media and equivalent activity in acidic electrolyte compared to Pt. In addition, I will talk about our recent work about nanomaterials for Li-ion/Na-ion batteries, as well as wastewater treatment.
