Titanium dioxide nanoparticles are an oxide which is widely used as a photocatalyst. It also used in solar cells development based on DSSCs (Dye- Sensitized Solar Cells) and rechargeable batteries development for automotive and electronic applications. It has high chemical stability and nontoxic materials. It can be synthesized through mechanical, physical and chemical methods. Commercially produced nanotitania does not exhibits a high efficiency when applied in various applications, thus requiring further development. On the other hand, there are still few studies that focus on the comparisons of various synthesis methods, thus a comparative review is required for further developments of the synthesis of titanium dioxide nanoparticles. In this thesis report, A study was conducted by collecting various sources to provide general information regarding titanium dioxide nanoparticles. The information contains an explanation of nanoparticles, titanium and the source of titanium raw materials, characteristics of titanium dioxide nanoparticles, applications of titanium dioxide nanoparticles and the process of producing titanium dioxide from ores. Afterward, collection of literatures that discuss the methods of synthesizing titanium dioxide nanoparticles, was conducted. Process parameters and the experimental results for each synthesis method which includes size, morphology, and structure of the nanoparticle of titanium product are summarized in a tabular form. Furthermore, an analysis was carried out regarding the strengths, weaknesses and prospects of research that can be carried out in the future. The result of the review shows that the characteristic of synthesized titanium dioxide nanoparticle was dependent on the synthesis method used. The synthesis process can be carried out by mechanical and mechanochemical, sol-gel, hydro/solvothermal, sonochemical, microemulsion, microwave heating, and spray pyrolysis methods. Each synthesis method has advantages and disadvantages both in terms of the effectiveness of the process route and the characteristic of the product. Research prospects for each of the synthesis method are still quite open and aspects that can be investigated have been identified in this literature review. In this literature review, is also give a process route that can be used for titanium dioxide nanoparticle’s production on a larger scale with certain product’s characteristics.
