“…The N 2 adsorption/desorption isotherm of TNS is shown in Figure 2. The specific surface area of TNS measured by nitrogen adsorption is 325.08 m 2 /g, and the main mesopore volume is 1.1 cm 3 /g, which is almost consistent with the existing research (Lu et al 2015). According to the graph, the nitrogen adsorption/desorption isotherm of TNS is of type IV, with a larger H3 hysteresis loop, classified by IUPAC, which represents the mesoporous structure.…”

“…During the reaction, a large number of Ti-O bonds are broken, causing the TiO 2 nanoparticles to be peeled off into smaller planar nanoplates. These smaller planar nanoparticles flakes are combined together to form larger flat nano flakes (Lu et al 2015), and finally Na (I) is embedded in the titanate nano-layers by NaOH alkalization, which provides a site for ion exchange.…”

In recent years, TNS has attracted wide attention because of its simplicity in synthesis and high efficiency in ion exchange. The adsorption of cesium ions in aqueous solution by TNS was investigated in this stud. Results show that the removal rate of Cs (I) is about 88% when pH = 5.00 ± 0.05, C0 = 10 ppm and CTNS = 0.1 g/L. The adsorption equilibrium is reached in about 20 minutes and best fits pseudo-second order model, R2 = 0.9998; Compared with the Freundlich isotherm adsorption model and Temkin model, the Langmuir model has the best fitting effect, R2 = 0.9903. The fitting results show the maximum adsorption capacity of TNS for Cs (I) is 200.00 mg/g. The main adsorption mechanism of TNS to cesium ion is ion exchange. Therefore, TNS can be used as a potential adsorbent for effectively adsorbing Cs-containing wastewater.

“…The three crystalline forms of Titania can be synthesised by various techniques. These include dry methods such as flame synthesis [4][5][6][7], chemical vapour deposition [8] and wet chemistry methods such as the chloride (TiCl 4 ) method [9], hydrothermal processing [2,[10][11][12][13][14][15][16][17][18] and the sol-gel methods [19][20][21][22][23][24][25]. The sol gel process is predominant because it has got distinct advantage from others due to mixing of the constituents at the atomic scale; simplicity of operation and low cost [3,23].…”

Nanocrystalline powders of TiO 2 xerogel and aerogel were prepared by using acidmodified sol-gel approach. For TiO 2 aerogel material (TA), the solvent was high temperature supercritically extracted at 300°C and 100 bars. However, the TiO 2 xerogel material (TX) was dried at 200°C and ambient pressure. The effects of the drying processes on the crystalline structure, phase transformation and grain growth were determined by Raman spectroscopy, SAED and Xray diffraction (XRD) analyses using Rietveld refinement method. The TiO 2 aerogel was composed of anatase crystalline structure. The TiO 2 xerogel material was composed of anatase, brookite and small amount of amorphous phase with anatase as dominant phase. The TX sample still contains a relatively high concentration of carbon than that of TA, indicating the amorphous character of TiO 2 xerogel. These materials were applied as catalyst for the degradation of indigo carmine in aqueous medium. Photo-degradation ability of TA and TX was compared to the TiO 2 commercial Degussa P25. The photo-catalytic results showed that the degradation efficiency was in the order TA > P25 > TX. The photo-degradation of indigo carmine followed pseudo first order reaction kinetics.

For a sustainable development, chemical processes should be designed around the use of renewable raw materials (RRM). The aim of this study is using limonene, chosen as example of an industrial by-product, to prepare limonene oxides, carvone, carveol, carvacrol and terephthalic acid, all of great industrial interest, with values of one to two orders of magnitude greater than limonene and compare the results obtained with conventional, microwave or solar activation in order to decrease the environmental impact of the process. The reactions were carried using catalysts based on materials of low toxicity, i.e. iron, manganese, titania and sepiolite. A number of techniques were used to characterise the compositional, structural and textural proiperties of the catalysts used. The results of this research indicate that for similar conversions conventional activation requires the highest energy expenditure, related to a negative environmental impact, while the use of microwave heating greatly reduces the reaction times and solar activation proves to be a very competitive and indeed the most environmentally friendly activation method.
