Facile mild hydrothermal treatment for surface functionalization of carbonized sawdust

This work illustrated the preparation of highly dispersive carbonized sawdust by surface functionalization through a facile mild hydrothermal treatment with an aqueous mixture of reactants, potassium persulfate and potassium hydroxide (KPS:KOH), at 160 °C. The dispersion, morphological and purity an...
