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–α-hydroxy–carboxylato titanium complex, an intermediate precursor mass at external temperature of 500°C, 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. ► Facile combustion method has been developed for the preparation of ultra-fine TiO2. ► PTC as a precursor has not been employed so far in the combustion synthesis of TiO2. ► Ratio of Ti to TA plays a vital role in the formation of TiO2. ► Circular pores observed on the TiO2 layers appear to be interesting. ► This method can be espoused for the preparation of other metal oxides.
