The air pollution has a great impact on the social and economic aspects all over the world. Thus, the interaction of materials with the atmosphere has received increased attention nowadays. In order to estimate the impacts of air pollution on the solid surfaces a suitable scientific basis is developed and the well known Reversed Flow - Inverse Gas Chromatography, RF- IGC, is used. This dynamic experimental technique leads to very interesting experimental results through the determination of some important physicochemical quantities. The solids studied were Pentelic marble, white TiO2 pigment, ceramic and the gases were NO2 and C2H2. The synergistic effects between acetylene and nitrogen dioxide were also investigated. Through the curves obtained for each adsorption quantity determined versus time, one can easily and accurately conclude the result of the pollution impact on every solid mentioned above. The surface topography and the mechanism of deterioration can also be studied. All the above answer in detail to the questions of where, when and how the influence of gas pollutants on materials of cultural heritage takes place.

Preparation Process

In the experiment, the tetrabutyl titanate and samarium trinitrate were used as raw material, samarium doped TiO2 powder was prepared by sol-gel method. Main factors that affect the TiO2 nanoparticles, such as catalyst, ratio of raw materials, and calcination temperature of the preparation process were studied. TiO2 powder was characterized by using XRD, UV-vis, IR to determine the crystal structure, grain size and spectral properties. The results show that, the amount of catalyst is 50mg, the calcination temperature is 500 °C, samarium doping ratio is 0.4%, and the visible light photocatalytic degradation time at 60min, the degradation of methyl orange solution rate of 20mg/L can reach 42.8%. Samples with anatase as the main, in the catalyst preparation process, due to the synergistic effects of samarium doping, the modified TiO2 absorption band of different redshift, enhanced the catalytic activity of TiO2 visible light.
