“…shows the XRD patterns of the prepared Fe 2 O 3 as well as the cyanamide-modified Fe 2 O 3 samples with various initial mol ratios of cyanamide to the iron precursor (x = 2-10). All the prepared Fe 2 O 3 and cyanamide-modified Fe 2 O 3 samples exhibited the characteristic diffraction peaks of Fe 2 O 3 (Cao & Zhu 2011;Chen et al 2012;Cornell & Schwertmann 2003;Li et al 2013Li et al , 2009Liu et al 2012;Mirbagheri et al 2014;Pradhan et al 2013;Roslan et al 2014;Sundaramurthy et al 2012;Thomas at al. 2015;Xu et al 2013;Yu & Kwak 2012;Zhang et al 2011).…”

“…All samples exhibited absorption peaks at ca. 390 nm, attributing to the Fe-O bond (π-3d) due to the ligand-metal charge transfer (LMCT), while peaks around 500-800 nm would be due to the d-d transitions of the Fe-Fe bond (Pradhan et al 2013;Roslan et al 2014). It was obvious that the addition of cyanamide increased the absorption level at ca.…”

“…40% of visible light. Since it is also stable and relatively cheap, Fe 2 O 3 has been widely explored for various photocatalytic applications such as water splitting reactions (Lin et al 2011;Qiu et al 2014;Sivula et al 2011), degradation and decomposition of dyes (Liu et al 2012;Sundaramurthy et al 2012;Xu et al 2013;Yang et al 2012) and other organic pollutants (Cao & Zhu 2011;Li et al 2009;Roslan et al 2014), as well as for some selective oxidation and polymerization reactions (Karunakaran & Senthilvelan 2006;Stroyuk et al 2007). The addition of Fe 2 O 3 onto another semiconductor photocatalyst such as TiO 2 has been also reported to give a significant contribution to improve the activity of the TiO 2 semiconductor (Cheng et al 2017;Lee et al 2017;Mou et al 2012).…”

Cyanamide as the source of carbon and nitrogen was used to modify iron(III) oxide (Fe2O3) photocatalyst. While X-ray diffraction (XRD) patterns confirmed that the cyanamide-modified Fe2O3 photocatalysts have comparable crystallinity to that of the unmodified Fe2O3, the diffuse reflectance ultraviolet-visible (DR UV-vis) spectra obviously showed additional light absorption around 500-800 nm on the cyanamide-modified Fe2O3, resulting in a better absorption capability under visible light irradiation. The presence of cyanamide modifier decreased the fluorescence emission intensity of Fe2O3, implying the reduced electron-hole recombination on the Fe2O3 and/or blocked emission sites by the modifier. The presence of carbon and nitrogen on the modified Fe2O3 photocatalysts was confirmed by the elemental analyzer. Photocatalytic activities of Fe2O3 and cyanamide-modified Fe2O3 were then evaluated for degradation of phenol under UV and visible light irradiation. Modification of Fe2O3 with cyanamide significantly improved the degradation of phenol from 30 to 75% under UV light irradiation and from 0 to 80% under visible light irradiation. Photocatalytic degradation of phenol was also investigated in the presence of urea or formaldehyde or both urea and formaldehyde. Even though the percentage of phenol degradation decreased in the presence of other pollutants, it was demonstrated that cyanamide modified iron(III) oxide photocatalysts still gave good activity towards degradation of phenol even in the presence of other organic pollutants.

“…After TiO 2 doping different valence states of metal ions, especially for metal ions with larger ionic radius would cause lattice distortion. The resulting would improve the separation of electron-hole pair and photo-quantum efficiency [7][8][9][10]. Choi et al conducted a systematic study on 21 metal ions doped in TiO 2 colloids, and Fe 3+ was found to be the most effective dopant for enhancement of photo-activity [11].…”

Abstract. The Fe doped TiO 2 (FET) gels were synthesized by different ferric salts and analyzed by thermal gravimetric analyzer and X-ray diffraction. The TG curves show that the valence states of Fe had a great influence on the preparation of FET gels, Fe 3+ was easy to replace titanium atoms to form lattice and the anatase phase was effectively established when the calcination temperature over 400 ˚C.The XRD spectra indicates that the anatase phase constantly changed into the rutile phase when the calcination temperature over 600 ˚C and the nitrate is beneficial to the formation of mixed crystal.
