“…TiO 2 has been widely studied regarding various applications, utilizing the photo catalytic and transparent conductivity, which strongly depend on the crystalline structure, morphology and crystallite size [8]. TiO 2 nanoparticles have been prepared by different methods such as, chemical precipitation method [9],chemical vapour deposition (CVD) [10], the sol-gel technique [11], sputtering [12], hydrolysis, micro emulsion method [13], spray deposition [14], aerosol-assisted chemical vapour deposition [15], thermal plasma [16], hydrothermal method [17], microwave assisted hydrothermal synthesis [18], solvothermal method [19] and flame combustion method [20]. Among these methods sol-gel method is a simple method to synthesis TiO 2 nanoparticles.…”

Nanoparticles of titanium dioxide doped with Fe2+ ions have been synthesized via sol-gel technique using Titanium tetraisopropoxide (TTIP) and ferrous sulphate as a precursors. The synthesized nanopowders were characterized by Powder X-ray Diffraction (PXRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), Ultraviolet Visible (UV-Vis) and Photoluminescence (PL) Spectroscopy. PXRD pattern indicates the presence of pure crystalline anatase phase TiO 2 with average crystallite size of 14 nm. FTIR spectra showed the vibrational bands of Ti-O networks. The morphology of the as prepared samples and chemical constituents of the nanoparticles studied using SEM and EDAX analysis. From the UV-Vis spectra and PL spectra the optical properties of TiO 2 were studied and discussed.

INTRODUCTIONOver two thirds of Earth's surface is covered by water; less than a third is taken up by land. As Earth's population continues to grow, people are putting ever-increasing pressure on the planet's water resources. In a sense, our oceans, rivers, and other inland waters are being "squeezed" by human activities-not so they take up less room, but so their quality is reduced. Poorer water quality means water pollution. We know that pollution is a human problem because it is a relatively recent development in the planet's history: before the 19 th century Industrial Revolution, people lived more in harmony with their immediate environment. As industrialization has spread around the globe, so the problem of pollution has spread with it. When Earth's population was much smaller, no one believed pollution would ever present a serious problem. It was once popularly believed that the oceans were far too big to pollute. Today, with around 7 billion people on the planet, it has become apparent that there are limits. Pollution is one of the signs that humans have exceeded those limits.Water pollution can be defined in many ways. Usually, it means one or more substances have built up in water to such an extent that they cause problems for animals or people. Water pollution almost always means that some damage has been done to an ocean, river, lake, or other water source. A 1969 United Nations report defined ocean pollution as: "The introduction by man, directly or indirectly, of substances or energy into the marine environment (including estuaries) resulting in such deleterious effects as harm to living resources, hazards to human health, hindrance to marine activities, including fishing, impairment of quality for use of sea water and reduction of amenities."Most water pollution doesn't begin in the water itself. Take the oceans: around 80 percent of ocean pollution enters our seas from the land. Virtually any human activity can have an effect on the quality of our water environment. When farmers fertilize the fields, the chemicals they use are gradually washed by rain into the groundwater or surface waters nearby. Sometimes the causes of water pollution are quite surprising. Chemicals released by smokestacks (chimneys) can enter the atmosphere and then fall back to earth as rain, entering seas, rivers, and lakes and causing water pollution. That's called atmospheric deposition. Water pollution has many different causes like: Sewage, Nutrients, Chemical waste, radioactive waste, Oil pollution, Plastics and Alien species. The common pollutants include toxic organic compounds like chlorinated and non-chlorinated aliphatic and aromatic compounds, dyes, inorganic compounds like heavy metals, noxious gases like NO x , SO x , CO and NH 3 , and pathogens like bacteria, fungi and viruses. ABSTRACTThe growth of industry worldwide has extremely increased the generation and accumulation of waste by products. This has caused severe environmental problems that have become a major concern. Because of this, photo-catalytic polluta...

“…When used as anode material for LIBs, the anatase TiO 2 has many advantages over other materials such as the commercial carbons. First, the two-way channels parallel to a and b axes in the anatase TiO 2 [9] provide fast Li insertion/extraction pathways. Second, the negligible volume change of TiO 2 electrodes during the insertion/ extraction of lithium ions guarantees good cycling stability of the batteries [10].…”
