Abstract EN
One-dimensional calcium oxide (CaO-) based titanium dioxide (TiO2) nanotubes were successfully synthesized through a rapid electrochemical anodization and chemical wet impregnation techniques.
In this study, calcium nitrate solution was used as a calcium source precursor.
The reaction time and concentration of calcium source on the formation of CaO-TiO2 nanotubes were investigated using field emission microscopy, energy dispersion X-ray spectroscopy, and X-ray diffraction.
The adsorption capacity of CO2 was determined by thermal gravimetric analyzer.
A maximum of 4.45 mmol/g was achieved from the CaO-TiO2 nanotubes (6.64 at% of Ca).
The finding was attributed to the higher active surface area for CaO to adsorb more CO2 gas and then formed CaCO3 compound during cyclic carbonation-calcination reaction.
