The development of carbonaceous materials such as biochar has triggered a hot spot in application. In this study, new type char carbon was developed from raw cigarette filter rods (CFRs) via carbonization process under moderate conditions (T = 550 °C; tres 1 h) (CFR carbon). produced characterized by ATR-FTIR (Attenuated total reflectance—Fourier-transform infrared) spectroscopy, XRD (X-ray diffraction) analysis, GC-MS (Gas Chromatography–Mass Spectrometry), FESEM-EDS (Field-Emission Scanning Electron Microscopy—Energy-dispersive X-ray spectroscopy) technique, XPS photoelectron spectroscopy), and N2 adsorption/desorption (BET) measurements. obtained material is rich oxygen-containing functional groups (i.e., C=O, C–O, –C(=O)–CH3, C–O–C, C–OH, O=C–O, with chemisorbed oxygen), containing significant amounts calcium (that originates CaCO3) silicon (Si), generated reduction SiO2. It found that the formation char(C)/n-alkane composite makes CFR have high compressive strength improvement. Moderate contributed to creation fairly specific surface area (320.93 m2/g), exhibiting complex hierarchical structure Type I/IV(a) isotherm, associated micro-/mesoporous material. addition, more directional extensions research for future work were proposed, including implementation electrochemical research.
