摘　　要：The hydrothermal/soft templating method is an effective way to synthesize ordered mesoporous carbon(OMC),yet the mechanism of this strategy is not well illustrated.Herein,a hydrothermal temperature-controlled approach is developed to precisely synthesize OMCs with well-defined morphologies from liquefied wood(LW).As the hydrothermal temperature increases from 130 to 210◦C,the hydrophilicity of the hydrophilic blocks decreases accompanied by the increase of the rel-ative volume of the hydrophobic block,resulting in the packing parameter p of micelles changing from p≤1/3 to 1/3<p<1/2,which transforms the micelle’s structure from spherical to cylindrical.Additionally,accelerated nucle-ation occurred with the increased hydrothermal temperature.When the rate of nucleation is matched to the self-assembly of the composite micelles,the compos-ite micelles grow into worm-like morphology and an ordered p6m mesostructure.This hydrothermal temperature-controlled strategy provides a straightforward and effective approach for synthesizing OMCs with various morphologies from LW,addressing the previously insufficiently elucidated micelle formation mechanism in the hydrothermal/soft templating method.
