报告摘要:
As clean and sustainable energy conversion devices, proton-exchange membrane fuel cells (PEMFCs) are expected to play dominant role in future clean energy solutions for various applications, particularly for electric vehicles (EVs). However, the high cost of Pt catalyst is one of the main obstacles for the wide-spread commercialization of PEMFCs. Therefore, developing highly efficient low-Pt and non-Pt group metal (Non-PGM) catalysts are one of the key solutions to solve the above-mentioned challenges.
Here, I will present our recent progress in developing advanced electrocatalysts mainly for oxygen reduction reaction (ORR) in PEMFCs. Among the Non-PGM catalysts, Fe/N/C catalysts are considered one of the most promising ORR catalysts. One major breakthrough has been made by Dodelet et al, with activity and performance of Fe/N/C catalyst approaching to that of Pt. However, the durability of Fe/N/C catalysts is still insufficient for practical applications and its performance decay mechanism is still unclear. Very recently, we made a systematic study to verify whether iron is at the origin of the first rapid decay (stability problem) of the Fe/N/C catalyst for ORR in PEMFCs, which is important to find better ways to improve the durability of Fe/N/C catalysts. Moreover, other types of novel nanostructured NPM catalysts will also be discussed. At the same time, a series of low-Pt nanostructured electrocatalysts, synthesize by green chemistry and atomic layer deposition (ALD), including nanowires, nanotubes and single atoms, for fuel cells will also be presented. In the end, I will also briefly introduce our work beyond fuel cells, including Li-ion/Na-ion/Zn-ion batteries, solar water splitting for H2 production, and metal-air batteries.
