Prof. Keith J. Stevenson in ZIOC RAS
On October 5th 2016, in the ZIOC library, Prof. Keith J. Stevenson gave a talk on
Development of Advanced Tools for Catalyst Evaluation and Screening. Prof. Stevenson is
Director of the Skoltech Center for Electrochemical Energy Storage, Skolkolvo Institute of Science and Technology, Moscow. http://faculty.skoltech.ru/people/keithstevenson
The lecture dealt with the development of advanced research technologies and characterization of catalysts for various electrochemical processes, particularly those related to the environment-friendly energy conversion. Catalytic properties of nanoscale materials were discussed. Limitations of fuel cells as barriers to their successful commercialization were highlighted. Among new tools for the systematic evaluation of nanoscale catalyst performance in the environment-friendly energy conversion was suggested a simple, reliable and low-cost electrochemical method for detecting individual catalytic nanoparticles with a view to study homogeneity by catalyst size and activity. The approach is also useful for the catalyst size quantification. Peculiarities of mechanisms of various electrochemical processes such as oxygen hydrogenation in terms of the catalyst nanoparticle structure were discussed.
