Innovative Applications of Cerium Oxide-Based Materials in Civil Engineering, Automation, and Energy Sectors

Abstract

Cerium oxide materials exhibit remarkable properties, positioning them as highly effective, environmentally friendly solutions across diverse applications. This chapter provides a comprehensive overview of fundamental concepts and technological methodologies related to cerium oxide (CeO2) and doped ceria-based materials. Emphasis is placed on electrochemical deposition, spray pyrolysis, and the sol-gel approach for synthesizing thin and thick layers of ceria. The versatility of these materials is explored, spanning from corrosion protection layers and specialized ceramic elements for sensor applications to components for solid oxide fuel cells (SOFCs) and electrodes for water-splitting cells. Additionally, the chapter delves into the promising applications of recently developed ceria-based nanomaterials in various fields, marking some advanced methods for CeO2-based materials synthesis. The key findings are succinctly summarized in the concluding section.
