Abstract |
Conversion of solar energy into transportable liquid fuels has been an important research theme in physical sciences for the last decade. Many artificial photosynthetic devices have been built with numerous iterations and enhancements, yet all fall short of the biological machinery. Especially, the gap in the performances of enzymes and their inorganic counterparts is large, therefore promoting the need for the development of efficient catalysts and deep understanding of the catalytic processes involved in the solar-to-fuel cycle. In the current presentation, an advanced electrochemical surface analysis platform will be introduced, which enables surface-selective and potential sensitive redox activity analyses of catalyst surfaces. Several case studies will be shared including important catalysts for the oxygen evolution and the hydrogen evolution reactions. Recent example of the application of the analytical technique to photo-catalysts will also be shared. |
