Despite considerable efforts undertaken in a rapidly developing area of materials research, synthesis of TiO₂ nano-powder via green methodologies has a great scientific importance. Here, we present a novel green approach for the synthesis of TiO₂ nano-powder by solution combustion process using titanium peroxo complex and tartaric acid (TA) as an intial precursor. The water-soluble peroxo-¦Á-hydroxy-carboxylato titanium complex, an intermediate precursor mass at external temperature of 500 ¡ãC, resulted in the oxide of pure anatase phase. This green process involves universal green solvent hydrogen peroxide and it minimizes the time, energy and cost of the production of TiO₂.
