Abstract

This PhD thesis goes from the fundamentals of electrochemical reactions to the application. First, we evaluate the Electrochemistry - Mass Spectrometry (EC-MS) setup for the fundamental mechanistic study of electrochemical reactions over metal surfaces. Among others, the electro-oxidation mechanism of ethanol over a platinum surface and the electrochemical reduction of nitrate to ammonia over Ti, Ag and bimetallic TiAg electrodes have been investigated. Furthermore, there have been collaborations using the EC-MS for other reactions that confirmed the sensitivity and versatility of this instrument in several applications. In the last chapter, we focus on the application of the acquired mechanistic knowledge in the nitrate electrochemical reduction over TiAg for more practical purposes using Ti hollow fiber electrodes.
