英文摘要: TiO2/N-100 photocatalyst was synthesized by hydrothermal reaction of amorphous anatase TiO2 and NH4OH at 100 C. The photocatalyst was characterized by FE-SEM, XRD, nitrogen content using elemental analyzer, UV-vis/DR spectroscopy and N2 adsorption at liquid nitrogen temperature. CO2 adsorption up to 30 bar was also investigated. The amount of CO2 adsorbed on TiO2/N-100 was 120 mg g-1 at pressure of 30 bar and temperature of 338 K, which was larger than that on commercially available TiO2 P25. The adsorption isotherm of CO2 on TiO2/N-100 can be well described by the Freundlich adsorption equation. On the basis of n value it was found that an interaction between CO2 molecules and TiO2/N-100 surface occurs according to chemisorption mechanism. The photocatalytic properties of the prepared material were determined in the synthesis of methanol from CO 2 in an aqueous solution. The maximum yield of methanol was equal to 20 μmol/g. The maximal methanol production rate was equal to 23 μmol h-1 g-1 and was higher than values reported in the literature by most of authors. © 2013 Elsevier Ltd. Citation statistics:
