Study of the Preparation of Folic Acid-Derived Carbon and its Capacity to CO2 Capture
The large emissions of the greenhouse gas CO2 have deeply affected human survival and development.According to the national energy development strategy,the high-capacity capture of CO2 mainly takes up the alleviation of environmental pollution and production of high-value-added chemicals such as cyclic carbonates.In this work,the folic acid-derived activated carbon was obtained after carbonization and activation,which employed low-cost folic as precursor and KOH as activator,exhibiting excellent CO2 adsorption performance.We performed a series of means to understand the physical,texture and structural characteristics of the folic acid-derived activated carbon comprehensively,including BET,SEM,SEM-EDS,XRD,Raman,and XPS.Subsequently,the CO2 capture performance of folic acid-derived activated carbon were evaluated under 1 bar 0℃and 1 bar 25℃.Additionally,the indispensable relationship between the structural features of the activated sample and its high adsorption capacity was further explored.In the context of carbon neutrality and emission peak,it is believed that the work will provide technical and theoretical support for the achievement of negative carbon sink targets in the industrial field.
