TiO 2 supported on reed straw biochar as an adsorptive and photocatalytic composite for the efficient degradation of sulfamethoxazole in aqueous matrices
TL;DR: TiO2/pBC showed stable photocatalytic activity after five sequential PCD cycles and the biochar was able to promote further PCD on TiO2 by adsorbing SMX and intermediates thereby prolonging the separation lifetime of electrons (e-) and valence band hole (h+).

Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
