Special Issue Information

Dear Colleagues,

Nanomaterials derived from biomass have emerged as a cutting-edge solution to address global challenges in sustainable energy and environmental protection. Combining the natural abundance, eco-friendliness, and tunable properties of biomass with the unique advantages of nanotechnology—such as high surface area, tailored porosity, and enhanced functionality—has unlocked tremendous potential for innovative applications.

This Special Issue focuses on the design, synthesis, and applications of nanostructured biomass-based materials in two key areas: energy storage (e.g., battery electrodes, electrolytes, and supercapacitors) and environmental remediation (e.g., heavy metal adsorption, water purification, and air pollution control). The convergence of biomass resources and nanotechnology not only addresses resource sustainability but also fosters the development of multifunctional, high-performance materials that align with global carbon neutrality and circular economy goals.

Scope of the Special Issue

Nanostructured Biomass-Based Materials for Energy Storage

  • Biomass-derived nanostructured carbon materials for lithium-ion, sodium-ion, and potassium-ion batteries.
  • Nanostructured biomass-based materials as high-performance supercapacitor electrodes.
  • Biomass-derived solid or gel polymer electrolytes with improved ionic conductivity.
  • Mechanistic insights into the electrochemical performance of biomass-based nanomaterials.

Nanostructured Biomass-Based Materials for Environmental Remediation

  • Nanostructured biomass materials for the adsorption and removal of heavy metals from water and soil.
  • Biomass-derived nanomaterials for the catalytic degradation of organic pollutants.
  • Porous and functionalized biomass-based nanomaterials for air purification and gas adsorption.
  • Recyclability and regeneration of biomass-based nanomaterials for long-term environmental applications.

Synthesis and Characterization

  • Advanced methods for the nanostructuring and modification of biomass materials (e.g., pyrolysis, hydrothermal treatment, and chemical activation).
  • Structure-property relationships of biomass-derived nanomaterials.
  • Characterization techniques for nanomaterials: morphology, porosity, chemical composition, and electrochemical behaviour.

Synergistic Applications and Future Perspectives

  • Dual-function biomass-based nanomaterials for simultaneous energy storage and pollutant remediation.
  • Challenges and strategies for the large-scale production of biomass-derived nanomaterials.
  • Life-cycle assessment, sustainability, and circular economy considerations of biomass nanomaterials.

Why Focus on Nanostructured Biomass-Based Materials?

Sustainable and Renewable: Biomass serves as an abundant, low-cost feedstock, contributing to resource sustainability.

Enhanced Performance: Nanostructuring improves specific surface area, reactivity, and functionality, making these materials highly efficient.

Eco-Friendly Solutions: Biomass-based nanomaterials are biodegradable and have minimal environmental impact.

Multifunctionality: Their versatility allows simultaneous application in energy storage and environmental protection, supporting global sustainability goals.

By combining nanotechnology with biomass resources, these materials provide innovative pathways to develop high-performance, low-cost, and sustainable solutions for energy and environmental challenges.

The rampant growth of Spartina alterniflora has been wreaking havoc on the coastal ecosystems, leading to a serious environmental challenge in recent years. One potential solution to this issue involves converting Spartina alterniflora into activated carbon, offering a potential remedy for pollution while creating value in energy storage applications. Herein, through a facile carbonization process with sodium hydroxide activation, we successfully transformed obsolete Spartina alterniflora into a porous carbon material (called SAC) and its nitrogen-doped derivative (denoted as SANC) by using melamine as the nitrogen source in a similar procedure. The amorphous structure of these materials was confirmed to enhance lithium-ion storage and electrolyte permeation, making them ideal for use as anodes in lithium-ion batteries. As a result, both SAC and SANC, derived from Spartina alterniflora, exhibited outstanding electrochemical performance including high capacity (456.7 and 780.8 mA h g−1 for SAC and SANC, respectively, at the current density of 6 mA g−1), excellent rate performance (from 6 to 600 mA g−1) and long-term cycling stability. Notably, compared to SAC, its N-doped derivative SANC showed superior properties in the battery (retaining a reversible capacity of 412.9 mA h g−1 at the current density of 6 mA g−1 even after 600 repeated charge–discharge cycles), demonstrating the significantly positive impact of heteroatom doping. This work not only offers a strategy to mitigate environmental challenges but also demonstrates the potential for converting waste biomass into a valuable resource for energy storage applications.

The transition to sustainable energy storage solutions has driven significant interest in supercapacitors, which offer high power density, rapid charge–discharge capabilities, and exceptional cycle stability. Biomass-derived carbon nanomaterials have emerged as compelling candidates for supercapacitor electrodes due to their renewable origins, environmental compatibility, and cost-effectiveness. This study explores recent advancements in tailoring structural properties, for example in preparation methods and activation, which are essential for efficient charge storage and rapid ion transport. Attention is given to the dimensional configurations—spanning 0D to 3D structures—and their impact on electrochemical behaviors. This review outlines the challenges faced in scaling up and optimizing these materials for practical applications, alongside an outlook on future research directions. By bridging the gap between material design and application demands, this work contributes to advancing sustainable supercapacitor technologies for a greener energy future. Full article
