A perspective on the preparation of value-added carbon materials from lignin

Abstract

The thermochemical conversion of lignin into different added-value carbon materials constitutes an alternative approach for valorization of this co-product that can be integrated in pulping and biorefinery processes. Such approach is based on the relatively high carbon content and the abundance of aromatic rings in the structure of raw and technical lignins. In this way, our research group have been preparing carbon molecular sieves, activated carbons, electrospun nanofibers, nanostructured and highly ordered carbons from different types of lignins during the last three decades.
