Synergistic Adsorption and Photodegradation of Hydrothermal Carbonation Carbon Derived from Lignocellulose for the Removal of Tetracycline from water- DataSet.zip

Hydrothermal carbonation carbon (HTCC) is emerging as a promising material for the adsorption and photodegradation of environmental contaminants. However, the chemical and structural properties of HTCC derived from different lignocellulose biomass have obvious impacts on adsorption and photodegradation. This work employed three different lignocellulose components, including cellulose, hemicellulose, and lignin, to synthesize HTCC at various hydrothermal temperatures and investigated their synergistic potential for adsorption and photodegradation. Compared to the HTCC derived from cellulose and hemicellulose, the HTCC derived from lignin demonstrated the optimal synergistic adsorption and photodegradation ability for TC degradation. The mechanisms of adsorption and photodegradation on lignin-derived HTCC were elucidated through the application of multiple characteristic techniques and electrostatic potential mapping. Characterization highlighted the crucial involvement of oxygenated functional groups presented on the surface of lignin-derived HTCC in TC adsorption. Moreover, the photodegradation of lignin-derived HTCC was found to follow a non-radical mechanism, characterized by the charge transformation occurring between the excited unpaired electrons of lignin-derived HTCC and TC adsorbed on its surface. This work clarified the differences in HTCC derived from different lignocellulose components on adsorption and photodegradation of organic pollutions, and highlighted the synergy of adsorption and photodegradation on environmental contaminants.
