TL;DR: In this paper, the growth and photocatalytic activity of TiO 2 hierarchical nanostructures by solvothermal method at different temperatures were investigated. And the results revealed that the morphology of the nanostructure can be effectively controlled as rose-like, chrysanthemum-like and sea-urchin-like only changing solvographic temperature.

TL;DR: The aim was to improve the CO(2) adsorption capacity of the carbon materials by increasing the porosity during the chemical activation process by increasingThe porosity was due to an increase of BET surface area and pore volume in all carbon materials.
Abstract: In this work, the CO2 capture capacity of different types of carbon nanofibers (platelet, fishbone, and ribbon) and amorphous carbon have been measured at 26 °C as at different pressures. The results showed that the more graphitic carbon materials adsorbed less CO2 than more amorphous materials. Then, the aim was to improve the CO2 adsorption capacity of the carbon materials by increasing the porosity during the chemical activation process.After chemical activation process, the amorphous carbon and platelet CNFs increased the CO2 adsorption capacity 1.6 times, whereas fishbone and ribbon CNFs increased their CO2 adsorption capacity 1.1 and 8.2 times, respectively. This increase of CO2 adsorption capacity after chemical activation was due to an increase of BET surface area and pore volume in all carbon materials. Finally, the CO2 adsorption isotherms showed that activated amorphous carbon exhibited the best CO2 capture capacity with 72.0 wt % of CO2 at 26 °C and 8 bar.
