The increasing global energy demands are intensifying dependence on fossil fuels, raising concerns about their limited reserves and the adverse environmental impacts associated with their use. Among the potential solutions, electrocatalysis offers sustainable and clean energy alternatives to address these challenges. In scientific terms, electrocatalysis refers to the acceleration of electrochemical reactions through the use of advanced catalysts, primarily in energy conversion and storage processes. Particular attention is given to the hydrogen evolution reaction (HER) due to its ability to generate hydrogen, a sustainable and clean fuel source. The efficiency of this reaction largely depends on the development of electrocatalytic materials capable of reducing the required overpotential and enhancing the reaction kinetics. Therefore, ongoing research and innovation in these materials are essential to advancing hydrogen production technologies. This undergraduate thesis aims to investigate electrocatalytic materials for the hydrogen evolution reaction (HER), utilizing Fourier-transform infrared spectroscopy (FTIR) as the primary analytical technique. Initially, an extensive literature review is conducted to understand the complex mechanisms and molecular behavior of catalytic reactions. In the experimental phase, catalysts are synthesized from transition metals and carbon-based materials, which are then examined using spectroscopic techniques. Subsequently, the resulting spectra are analyzed to explore chemical structures and functional groups. As a result, the correlation between material structure and catalytic performance is determined. Finally, the physicochemical and electrochemical properties of the synthesized materials are evaluated in order to assess their performance and suitability for hydrogen production.
