课题组王得丽教授邀请到了Abruña教授进行线上讲座，广受师生关注，共132人踊跃参与其中。

This presentation will deal with the development of new materials and operando methods for energy conversion with emphasis on electrocatalysis and fuel cells in

alkaline media. The presentation will begin with a brief overview of the methods employed with emphasis on the use of X-ray based methods and transmission electron microscopy (TEM) under active potential control. The utility of these methods will be illustrated by selected examples focusing on non-precious metal electrocatalysts for the oxygen reduction (ORR) andlydrogen oxidation (HOR) reactions, fuel cell testing, operando imaging of CUUPD and cathodic corrosion of Pt. The presentation will conclude with an assessment of future directions.
