My research focuses on the design of hydroxyapatite-based catalysts through Thermal Stimulated Polarization (TSP) for sustainable environmental applications. In particular, I investigate TSP-engineered materials for the conversion of CO₂ and N₂ into value-added products and the photodegradation of microplastic pollutants. The research also involves the exploration and development of novel materials with tailored properties through TSP processing.
