Our research group cannot find suppliers of TiCl4 locally and our access to school laboratory is very limited due to pandemic. We are looking for ways on how to synthesize TiO2-rGO composite for our study using simple equipment only. Would you please help us in this?

For your reference, here is the original method:

SYNTHESIS OF TiO2@rGO COMPOSITES

The TiO2-rGO composite will be synthesized via the typical chemical method. Reduced graphene oxide (0.1 g) and 260 mL of 0.1 M titanium chloride (TiCl4) aqueous solution will be subjected to magnetic stirring for 0.5 hours at 80˚C. The mass ratio of TiO2 to rGO is based on the results of several studies indicating that the optimum concentration for the latter is 2 wt % 13,14. Slowly, 260 mL of 0.4M NaOH will be added under constant stirring for 3 h. The mixture will be washed with deionized water and ethanol five times; the former is for adjusting the pH to 7 while the latter is for better dispersion of the molecules. The formed product will be recovered using filter papers. Finally, it will be dried at 80˚C for 4 h.
