Topic: Biomass-Derived Functional Materials for Energy Harvesting, Conversion, and Storage

The rapid depletion of fossil fuels and growing environmental concerns have spurred intensive research into sustainable energy technologies. Biomass, as an abundant, renewable, and carbon-neutral resource, offers a versatile platform for constructing advanced functional materials.

This Special Issue focuses on the rational design, synthesis, and application of biomass-derived materials in emerging energy-related fields, including triboelectric nanogenerators (TENGs), photocatalysis, rechargeable batteries, and supercapacitors. We invite contributions that explore the conversion of natural polymers (cellulose, lignin, chitin, etc.) and bio-waste into high-performance components—such as triboelectric layers, photoelectrodes, electrocatalysts, separators, electrode materials, and electrolytes—with emphasis on structure–property relationships, interfacial engineering, and device performance.

Mechanistic studies, scalable fabrication strategies, and life-cycle assessments are also welcome. By bridging fundamental materials science with practical energy devices, this collection aims to highlight the unique advantages of biomass-based materials in addressing the trade-offs between efficiency, durability, and sustainability.

We encourage original research articles, reviews, and perspectives that push the boundaries of green materials for next-generation energy systems.
