title: Synthesis of TiO2 Materials Using Ionic Liquids and Its Applications for Sustainable Energy and Environment.
abstract: Titanium dioxide (TiO2) has received significant attention because of the global climate change and the consumption of fossil fuel resources. Specifically, using TiO2 in photocatalytic applications, such as the removal of organic pollutants and a hydrogen production has become an important issue. Thus, many researchers have attempted to prepare highly active TiO2 materials using various synthetic approaches. Modifications of the conventional sol-gel method, such as the addition of surfactants, have been employed in synthetic procedures. Moreover, hydrothermal, solvothermal, sonochemical and microwave methods have also been used as alternative approaches. Recently, the use of ionic liquids represents a burgeoning direction in inorganic material synthesis. Ionic liquids are exceptional solvents consisting of ions possessing low vapor pressure and tunable solvent properties. This article reviews the preparation of TiO2 materials using ionic liquids with various synthetic approaches. Also, sustainable energy and environmental cleanup applications of TiO2 materials, including the treatment of hazardous organic substances and hydrogen energy derived from electrochemical methods, are discussed.
