“…Moreover, Xu et al indicated that the dye degradation on iron oxides/hydroxides is mainly occurred through a semiconductor photocatalysis. Similar conclusion is reported by other authors in photocatalytic degradation of the pyrene [20], polyethylene [21] polystyrene [22] and aniline [23]. Accordingly, the photocatalytic degradation of AO7 in the presence of ␣-FeOOH could be explained by formation of photoinduced charge carriers (electron-hole pairs).…”

“…Higher photocatalytic activities of oxides could be obtained by metal doping such as Ce [12] and Ti [13], and it could also be obtained by non-metal doping such as N [14,15], S [16,17], P [18], and C [19,20]. Recently, boron-doping on oxides begins to attract attention in electrochemical and functional materials application [21]. However, most studies focused on TiO 2 , and little was done about Mn oxide.…”

The effect of boron doping on the photocatalytic activity of manganese (Mn) oxide in aniline degradation was investigated. Mn oxide was synthesized by the reaction of MnCl 2 with KMnO 4 and boron-doped Mn oxide (occluded-B-Mn oxide or oc-B-Mn oxide) was prepared by the reaction of MnCl 2 with KMnO 4 in the presence of boric acid. The structural formulas of the Mn oxide and the oc-B-Mn oxide were K 0.04 MnO 1.90 (H 2 O) 0.54 and K 0.04 B 0.01 MnO 1.87 (H 2 O) 0.61 , respectively. Their physicochemical properties were characterized by XRD, TEM, BET and UV-Vis absorption spectra. The photocatalytic activity was evaluated by aniline degradation in aqueous catalyst dispersions under UV light radiation. Discussion of the results showed that the higher photocatalytic activity of the oc-B-Mn oxide may be attributed to the synergetic effect of light absorption, the specific surface area and the suppression of recombination of electron-hole pair.

“…However, polymers like PS can cause serious environmental and economic problems because they do not bio- 2 TiO degrade well and may be pollution sources. Thus, various polymer recycling methods were developed in the last few years [8,13,[16][17][18][19][20][21][22]. Very small beads of extruded polystyrene (EPS) can be manufactured that contain between 4% and 7% of the blowing agent (usually pentane or butane).…”

The synthesis and characterization of a new nanocomposite material that was prepared from recycled expanded polystyrene (EPS) and titanium dioxide (TiO₂) is reported here. The EPS was obtained from chemical reagent box insulation. To obtain the nanocomposite, these materials were dispersed in a solvent, mixed with TiCl₄ and heated. The resulting new material was characterized with SEM, TEM, TGA, BET, Raman and IR techniques. The Raman and IR spectra provided complementary information regarding the structure of the nanocomposite. The Raman spectra were used to identify the crystalline structure of TiO₂ in the nanocomposite. In contrast, the IR spectra were used to identify the organic portion of the nanocomposite. The TEM images indicated that the nanocomposites had an average particle size of 6 - 12 nm. In addition, the adsorption and photocatalytic properties of the new material were evaluated. The EPS/TiO₂ nanocomposite was efficient at degrading methylene blue (MB) dye solutions under UV irradiation. Furthermore, according to thermal analysis, this material had greater polymer stability due to the incorporation of TiO₂.
