Description Carbon dioxide is among the main greenhouse gases and its high concentrations in the atmosphere contribute to climate changes. The electrochemical reduction of CO2 allows to convert carbon dioxide, water and renewable energy into those chemical compounds that today are derived from fossil sources. The manufacture of systems for the industrial development of this technology requires a solid modeling support. In this work of applied theoretical research, the thesis student will learn the fundamentals underlying mass transport phenomena. Using multiscale modelling software (e.g., COMSOL, OpemFoam, etc.), the student will simulate different operating conditions (catalysts, electrolytes, applied electric potential, carbon support matrix) used in the process to guide the experimental design of CO2 conversion systems. In particular, the purpose of the thesis is the in-depth study of
concentration gradients within the aqueous electrolyte towards the definition of the best geometry for the generation of a specific reaction product. In addition, electrocatalytic reactions at the electrode/electrolyte interface will be considered to provide insights on the best catalyst for experimental use.
Given the high amount of data generated during the study, the thesis student will acquire skills in data analysis using Python language and in data representation through Blender and the Office package.
Writing of the thesis in English is required.
Required skills An advanced knowledge of mass balances, chemical processes and transport phenomena is required.
A basic understanding of electrochemistry is required.
A basic understanding of solid-state physics is helpful
