I am working on rGO-doped TiO2 thin film for IR reflection. Can I make TiO2 film by Titanium trichloride??
4mL TiCl4 (99.9%, Sigma-Aldrich) was injected drop by drop into 16 mL cold anhydrous ethanol (stored in the fridge before use) with strong stirring to avoid local overheating of ethanol. After the solution cooled down to room temperature, 80 mL of anhydrous benzyl alcohol was added to the previous solution after cooling and stirred for 10 min. The original yellow solution became reddish after the addition of benzyl alcohol. The mixed solution was then transferred into a 200-mL vail, which was firmly sealed and stored without stirring in an oven at 85 °C for 12 hours. After heating for one hour, the solution became yellow again. The product TiO2 nanocrystals were then precipitated from the as-obtained solution by the addition of diethyl ether and isolated by centrifugation at 5000 rpm for 2 min. The solid was subsequently washed by adding anhydrous ethanol and diethyl ether, followed by a similar centrifugation step (5000 rpm for 2 min). This washing procedure was repeated for twice. The solution is transparent and can be stable in air for at least 6 months without precipitation.
@rohit. Thanks for your valuable suggestion. Definitely I will work on it.
@ Deva Arun I know Titanium isopropoxide is the best for this but currently we dont have that. Thats why I am trying to make this using TiCl4
Sir,Titanium isopropoxide would be the best.since you could produce TiO2 easily.
Titanium trichloride on the other it is not easy to remove the chlorine atoms even at 350 deg c. It will have effect in film . Go for other such nitrates,acetates. You can use titanium trichloride at last .
Refer the literature before then proceed.
