Photoelectrochemical Water Splitting

Developing new strategies to harvest the sunlight’s energy has been one of my major objectives since early in my career as a researcher, and particularly photovoltaic and photoelectrochemical energy conversion have been drawing much of my attention. My research interests encompass not only the synthesis of new materials but also the development of new tools that could help us understand and adjust the complex processes that control the energy conversion.
My present research entails the development of a novel electrochemical platform to access energetic and kinetic information of the photoelectrocatalytic reactions occurring at the photoelectrode/electrolyte interface in-operando, a crucial piece of information that remains elusive to date and could reshape the photoelectrochemical-based technology. More specifically, I am probing the electrochemical surface characteristics of the electrode during the hydrogen and oxygen evolution reactions which reveals not only the electrochemical fingerprint of the reaction intermediates, but provides for the first time a direct measurement of the kinetics of the reactions. The main motivation for this line of research is to provide an unambiguous diagnosis of the parameters that constrain and direct the performance of state-of-the-art materials which will guide us in the design of precise surface engineering approaches to enhance the solar energy conversion.
