摘      要：This research is a follow-up to our recent discovery of a facile strategy for directly converting lignin powder into carbon *** this work,we report that the thermal pretreatment parameters in air can remarkably influence the formation and properties of the derived carbon *** pretreatment parameters(heating rate,temperature,and residence time)were systematically investigated and a conversion mechanism into carbon foam was *** the thermal pretreatment,relatively low temperatures,low heating rates,and short residence time hindered the formation of smooth and well-connected structures in the carbon *** overall product yields were similar regardless of the thermal pretreatment *** densities of the different carbon foams ranged 0.27–0.83 g∙cm^(−3).The carbon foams with the highest compressive strengths(10 MPa)were KLPC280-2-5,KLPC300-0-5,and ***280-2-5 exhibited a high iodine sorption value(182 mg∙g^(−1)).KLPC300-2-5 exhibited a specific capacitance of 158 F∙g^(−1) at a current density of 0.05 A∙g^(−1).The maximum evaporation rates in the solar vapor generation experiments were 1.05 and 1.38 kg∙m^(−2)∙h^(−1) under 100 and 150 mW∙cm^(−2) irradiation,*** good performances are attributed to the robust,porous,and continuous structure.
