Polymer‐Derived Ceramics: A Materials Platform for Advanced Energy and Environmental Applications

ABSTRACT Polymer‐derived ceramics (PDCs) have emerged as a versatile class of materials. Their unique processing route—from molecularly designed preceramic polymers to tailored ceramic architectures—enables precise control over composition, microstructure, and functionality. This review provides a comprehensive overview of recent advances in PDCs research, with emphasis on both fundamental aspects and practical applications. After introducing the chemical basis of preceramic polymers and their transformation into ceramics, we highlight strategies to tailor ceramic properties through elemental doping, nanostructuring, and composite design, including the development of high‐entropy systems. Particular attention is devoted to energy‐related applications, where PDCs serve as electrodes, electrolytes, catalysts, and functional supports in batteries, fuel cells, supercapacitors, thermoelectrics, and photocatalysis. Their role in environmental technologies is equally examined, spanning porous membranes for water purification, adsorbents for pollutant removal, gas separation, sensing, and advanced thermal insulation. The review also discusses recent progress in shaping technologies, such as additive manufacturing and fiber processing, which expand the design space for complex architectures. By integrating molecular‐level chemistry with multiscale processing and application‐driven design, PDCs are positioned as a key materials platform for sustainable energy conversion and environmental remediation. Finally, we outline current challenges and future opportunities aimed at enhancing their performance, scalability, and integration into next‐generation technologies.
