Abstract
Organic carbon and soot particles were produced in premixed ethylene-air flames and characterized with the aim to investigate their possible use as a low-cost solid sorbent for CO2 sequestration. Surface Enhanced Raman Spectroscopy (SERS) was employed to characterize particle composition, surface functionalities and medium range order of the carbonaceous particles sampled from the flame. SERS results, in addition to the analysis of particle charging processes occurring in flames, allowed inferring new insight on carbonaceous particles in the nucleation mode.File in questo prodotto:
