摘　　要：High applied thermal-stability and superior structural property for activated carbon adsorbent are extremely promising,which also is the determining short slab in volatile organic compounds(VOCs)adsorption applications.Herein,we develop the outstanding engineering carbon adsorbents from waste shaddock peel which affords greatly-enhanced thermal-stability and super structural property(S_(Lang)=4962.6 m2·g^(-1),Vmicro=1.67 cm^(3)·g^(-1)).Such character endows the obtained adsorbent with ultrahigh adsorption capture performance of VOCs specific to benzene(16.58 mmol·g^(-1))and toluene(15.50 mmol·g^(-1),far beyond traditional zeolite and activated carbon even MOFs materials.The structural expression characters were accurately correlated with excellent adsorption efficiency of VOCs by studying synthetic factor-controlling comparative samples.Ulteriorly,adsorption selectivity prediction at different relative humidity was demonstrated through DIH(difference of the isosteric heats),exceedingly highlighting great superiority(nearly sixfold)in selective adsorption of toluene compared to volatile benzene.Our findings provide the possibility for practical industrial application and fabrication of waste biomass-derived outstanding biochar adsorbent in the environmental treatment of threatening VOCs pollutants.
