Special Issue Information

Dear Colleagues,

This Special Issue aims to cover the latest breakthroughs in designing, fabricating, and applying advanced materials derived from cellulose. As the most abundant natural polymer, cellulose offers unparalleled potential for developing sustainable, high-performance functional materials. This collection seeks to capture the progress made in transforming cellulose through innovative techniques—including nanofabrication, chemical functionalization, and hybrid composite assembly—to unlock novel properties such as stimuli responsiveness, conductivity, antimicrobial activity, and enhanced mechanical strength.

Contributions will span novel synthesis and processing routes, the characterization of unique functional properties (e.g., self-healing, selectivity), and demonstrations in fields ranging from biomedicine to energy and environmental engineering. This Special Issue aims to showcase the expanding toolbox for cellulose modification, highlight how functionality and environmental responsibility can be synergistically achieved, and underscore cellulose's growing role in advanced material science.

Hexavalent chromium (Cr(VI)) is a highly toxic, non-biodegradable, and carcinogenic heavy metal. Its continuous release into aquatic ecosystems demands efficient, low-cost adsorbents. In this study, orange peel and peanut shell residues were thermally modified at 250 °C to enhance Cr(VI) remediation. Structural characterization confirmed that low-temperature calcination transforms raw agroindustrial wastes into functional biochars with a chemical architecture primed for cooperative Cr(VI) removal. N2 physisorption revealed a hierarchical mesoporous network with average pore diameters of 30.6 nm (calcined orange peel) and 15.4 nm (calcined peanut shell), despite low specific surface areas. Batch adsorption experiments demonstrated that removal kinetics reached equilibrium within 5 min for the modified biochars. Isotherm modeling showed that the adsorption process was best described by the Freundlich and Sips models. The calculated Sips heterogeneity factors (βS > 1) provided evidence of a cooperative multi-layer adsorption mechanism, attributed to the induced mesoporosity: initial chemisorption at high-energy sites facilitates the continuous anchoring of additional Cr(VI) ions without premature saturation. Ultimately, this study demonstrates that low-temperature calcination is a viable strategy to transform agricultural waste into kinetically efficient, cooperative adsorbents for wastewater treatment.
