“…The sorption mechanisms using carbon materials prepared from biomass wastes by emphasizing the relationship between the synthesis route or/and surface modification and the retention performance were discussed towards the removal of organic and heavy metal pollutants from water or air (NO(x), CO(2), VOCs, SO(2), and Hg(0)). Photocatalytic nanoparticle–coated biomass-based carbon materials have proved to be successful composites for water remediation. …”
