Main Objectives:
To study different H₂(g) production pathways based on (photo)electrocatalytic processes, employing Fe–M alloys (M = Ni, Co, Cu, and other metals), ABO₄ electroceramics (A = transition metals; B = Mo or W), and TiO₂-based materials doped with different metals (Pt, Cu, Ni, W, and Bi).
To construct prototype electrolyzers for laboratory-scale studies, using ultrasound-assisted technology as an innovative feature.
To design photocatalytic panels for H₂(g) production using solar radiation.
To establish physicochemical and biological treatment pathways for organic waste to enable the (photo)electrocatalytic production of H₂(g).
Market Potential and Technological Development:
The (photo)electrochemical production of green hydrogen (GH₂) has significant potential to meet the growing global demand for renewable energy. Research in this field has attracted considerable investor interest due to the potential of this renewable fuel for vehicles, energy storage, and a wide range of industrial applications. Therefore, as new technologies are developed and production costs decrease, the green hydrogen market is expected to expand considerably, along with the number of startups and spin-offs interested in the knowledge generated.
The (photo)electrochemical production of H₂(g) from renewable energy involves the synthesis and optimization of electrode materials, catalysts, and other components integrated into the devices. Research in these areas directly affects the efficiency, stability, cost, and operation of such devices, as well as the large-scale production of green hydrogen in compliance with commercial quality standards.
Furthermore, considering that the state is a major producer of readily fermentable organic waste, this material can be recovered and used as a feedstock for the production of H₂(g) and other fuels, thereby increasing the economic and technological feasibility of the process.
