    • In a typical synthesis, 0.85 mL of titanium(IV) ethoxide was injected to a mixture of 0.2 mL of aq solution of sodium chloride (4 × 10-4 M) and 50 mL of ethanol at ambient temperature in an inert atmosphere under magnetic stirring. Stirring was discontinued in ∼2 min to prevent the agglomeration of the particles. After sitting for two hours, the microspheres were collected by centrifugation, redispersed in 10 mL of ethanol, and then added into a mixture of 10 mL of DEG and 0.2 g PAA. The system was then heated to 200 °C, and the vapor of ethanol was released. TiO2 microcapsules formed when the opacity of original solution dramatically decreased, typically after 30 min. The solution was cooled to room temperature and cleaned with repeated actions of ethanol dilution and centrifugation. The microcapsules were finally dispersed in polar solvents such as ethanol or deionized water
