C arbon dioxide from flue gas removed using different types of solid sorbents, including porous zeolites, alumina, metal-
organic frameworks, silica materials and titanium dioxide. But, most of these conventional physisorbents suffer from
low CO2 adsorption capacities at relatively low carbon dioxide partial pressure and lower selectivity toward CO 2. Said issues
might be resolved by applying modifications in the surface chemistry of the porouse materials through impregnation with
functional groups including alkaline carbonates and various amines such as TEPA, TETA, DEA, and TEA. Porous materials
described above with high surface area and pore volume could accommodate larger amount of basic groups to capture CO2.
TiO2 nanotubes, exhibiting hydrothermally stable tubular structure, large pore system and specific surface area enabling
good accessibility for functionalization and adsorption are ideal mesoporous support for potential sorption applications. In
this work, the TiO2 produced by sulphate technology in Grupa Azoty Zakłady Chemiczne Police S.A., a chemical plant in
Poland. The preparation of titanate nanotubes carried out by hydrothermal method and functionalized with different kinds
of amines. The prepared adsorbents characterized by X-ray diffraction (XRD) and N2 adsorption –desorption at 77 K. The
morphology of the samples was observed with a scanning electron microscope (SEM) equipped with an energy dispersive
X-ray spectrometer (EDS). Textual properties defined by FTIR/DRS and Raman spectroscopy. CO2 adsorption/desorption
measurements for sample at 30C were carried using Netzsch STA 449 C thermobalance (Netzsch Company, Germany) on the
basis of the weight gain and loss during the sorption and desorption process.
