新型氮化碳材料的合成及其吸附性能的研究
Synthesis of New Carbon Nitride Materials and Their Absorption Properties
摘要
Abstract
Four graphitic-like carbon nitride materials (CN-EDA-CTC,CN-DCD, CN-UREA, CN-MEM) have been synthesized with ethylenediamine-carbon tetrachloride,dicyandiamide,urea and melamine as precursors,using attapulgite (ATP)as hard template.The new materials were characterized by XRD and TG,besides which,the N2 and CO2 absorption properties were tested repectively.The results indicated that the structure and properties of the precursors played an important role in the adsorption capacity of carbon nitride materials.In the four materials,the CN-UREA exhibited the highest capacity of CO2 with a capacity of 85.438 cm3/g at 0 ℃ and 58.931 cm3/g at 25 ℃.In addition,the results showed the attapulgite used as template in the new materials was removed thoroughly under magnetic stirring condition in 5% HF.The pore volumes and the CO2-absorption capacity of the samples were improved obviously.关键词
