Our research is directed toward the conversion of biomass and biomass-derived precursors into advanced functional materials for energy storage and energy conversion applications. Biomass-based materials are highly attractive because of their renewability, natural abundance, low cost, and environmental sustainability, making them promising candidates for future green energy technologies. We focus on the synthesis of porous carbons, heteroatom-doped carbons, and biomass-derived composites with tailored surface chemistry, porosity, conductivity, and structural stability. These materials are explored for applications in batteries, supercapacitors, and electrocatalysis, where they can serve as active materials, conductive frameworks, and support matrices. Our goal is to develop high-performance, sustainable, and scalable biomass-derived materials with enhanced capacity, energy density, electrochemical stability, and catalytic activity. Through this work, we aim to bridge waste valorization and advanced energy materials research, contributing to the development of cost-effective and environmentally benign energy technologies.
