Delignified wood aerogels as scaffolds coated with an oriented chitosan–cyclodextrin co-polymer for removal of microcystin-LR
Herein, a preassembled chitosan-cyclodextrin was used as a versatile coating onto delignified wood as an alternative for the removal of microcystin-LR. The addition of β-cyclodextrin proved to allow the nanowood scaffold to adsorb up to 0.12 mg g−1.

About this collection
The non-renewable nature of fossil fuels makes the current economic model unsustainable. The biorefinery concept, which takes traditional refineries as a starting point and adapts them to environmentally friendly processes based on bioresources as raw materials, has attracted the interest of a large number of scientists. Recent sustainable mobility outlooks indicate that electrification will coexist for a long time with combustion-based propulsion, thus entrusting biorefinery processes and the production of advanced biofuels with increasing importance.
Achieving a sustainable production of bio-based fuels, chemicals and materials requires a deep understanding of the chemistry behind biorefining processes. This themed collection aims to deepen the current knowledge of chemistry in biorefinery.
This collection is Guest Edited by Professor Alejandro Rodríquez Pascual (Universidad de Cordoba), Professor Carlos Martín Medina (Inland Norway University of Applied Sciences) and Professor Fabio Montagnaro (University of Naples Federico II).
