Sekretareva Group

protein on electrode

We aim to enhance the understanding of electron transfer processes within (bio)electrocatalysts and on the electrode/catalyst interface at the molecular level, and to design new (bio)electrocatalytic devices based on this new understanding. Our research bridge the disciplines of electrochemistry and (bio)inorganic chemistry and utilizes a range of electrochemical, spectroscopic and theoretical techniques, including single entity electrochemistry, protein film electrochemistry, electron paramagnetic resonance spectroscopy and quantum mechanical calculations, to address fundamental question of relevance to electrocatalysis.

Project description

Plasmonic metal nanoparticles are a novel emerging class of photocatalysts, superior to traditional semiconductor-based photocatalysts. Plasmonic nanostructures enable effective coupling of the light-harvesting and catalytic functions in one material and can promote thermodynamically demanding reactions due to large driving forces. Interaction of plasmonic nanoparticles with incident light leads to the excitation of so-called localized surface plasmon resonance (LSPR). Following LSPR excitation, different processes can enhance reaction rates on the surface of plasmonic material.  

Several parameters, such as size, shape and composition of plasmonic nanostructures strongly affect the lifetime of hot carriers, and consequently the reaction yields of the target product. Moreover, we have recently found that inert support materials on which plasmonic nanoparticles are commonly immobilized in electrocatalytic systems significantly influence the mechanism (hot carriers vs thermal effects) and efficiency of catalysis. Optimization of plasmonic catalysts by a traditional trial and error experimental approach in this multiparameter space is time-consuming and not cost-effective.

In this project, we aim to further investigate the mechanism of plasmon-enhanced electrocatalysis and to develop machine learning algorithms enabling fast identification of key parameters determining catalysis efficiency and, therefore, accelerated optimization of the catalyst towards the target product.

The applicant must hold a Ph.D. degree or an international equivalent within the field of Machine learning, Electrochemistry, Physical Chemistry, or a related field, or must have submitted their doctoral thesis for assessment in a relevant field prior to the application deadline. Documented experience in using machine learning approaches is required. Competence in plasmonic catalysis will be considered an advantage.

The assessment of applications is based primarily on the applicant's ability to conduct independent research based on scientific skills. Greater importance is attached to the quality of individual scientific work, than to the number of publications. The applicant must be sufficiently fluent in English to understand, discuss and communicate science on a high level.

Consideration will also be given to good collaborative skills, drive, creativity, and independence, how the applicant’s experience and skills complement and strengthen ongoing research within the group.
