“…In general, sorption is described using Freundlich isotherms, with sorption behaviour quantified as the specific sorption coefficient, K D (L/mg) (Nagaoka et al, 2002;Li et al, 2005). This coefficient is the ratio of equilibrium concentrations of a dissolved compound in a system containing a sorbent (AC or sludge or solids) and an aqueous phase and expressed as:…”

“…It was found that TiO 2 modification by non-metals such as carbon (3) causes light absorption in the visible region. For this purpose different inorganic and organic carbon precursors were used (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). Wide range of used precursors make it possible to widen TiO 2 activation range of irradiation to visible region.…”

Abstract:This work investigated the photocatalytic performance of TiO 2 photocatalysts modified with graphitic carbon under visible light with a very small component of UV. The graphitic carbon modification was conducted at 200-500 °C using thermal anthracene decomposition. The increase of calcination temperature leads to typical increase of crystallites size, decrease of the specific surface area and carbon content in modified samples. The characteristic peak for a skeletal in-plane vibrations of the anthracene ring located at 1522 cm -1 as well as the band at 1410 cm -1 assigned to C=C aromatic stretching vibrations mode were possible to observe. The analysis of the morphology using SEM confirmed the presence on new multi-layer carbonaceous flakes decorated with TiO 2 nanoparticles. TEM analysis and Raman studies proved the presence of graphitic structures covering the surface of the prepared TiO 2 /C photocatalysts. The highest photocatalytic activity, calculated on the basis of phenol photodegradation under visible light, was found for the photocatalyst modified with graphitic carbon at 400 °C (TiO 2 /C-400).

“…For this purpose many of the carbon precursors can be used, such as: n-hexane (2-4), poly(vinyl alcohol) or poly(ethylene terephthalate) (5-9), citric acid (10), cellulose (11)(12), glucose (13), sucrose (14)(15), poly(divinylbenzene) (16) and formaldehyde polymers (17)(18)(19)(20). Commonly used method to introduce carbon into TiO 2 lattice is thermal treatment.…”

Abstract:In this study a photocatalytic performance of new carbon-modified titanium dioxide photocatalysts was discussed. Benzene was used as carbon precursor. It was found that the photocatalytic activity of obtained samples increases with the increase of modification temperature and decrease of carbon concentration present in TiO 2 /C samples. This could be related to the kind of interactions between TiO 2 surface and carbon from thermal decomposition of benzene. The higher calcination temperature the less carbon deposits on the surface of modified samples and the higher probability of the Ti and C interaction confirmed by means of UV-vis/DR studies. It was proved that the photocatalytic activity of carbon modified titania nanomaterials strongly depends on carbon content in TiO 2 /C photocatalysts. Modification of starting TiO 2 with benzene is a promising method especially by taking into account the mineralization of phenol and the co-products of its degradation.
