I want to synthesis TiO2 photo catalyst by doping Boron and Nitrogen from H3BO3 and ammonia solution (NH3.H20) 2% and 5% precursors respectively. anyone who have the experience or knowledge please help me.

Prepare the titanium precursor: Titanium isopropoxide (TTIP) is commonly used as a precursor for synthesizing TiO2 photocatalysts. Dissolve TTIP in anhydrous ethanol to make a 0.1 M solution. Add the dopant precursors: In a separate flask, dissolve H3BO3 in deionized water to make a 2% solution. Similarly, dissolve NH3.H2O in deionized water to make a 5% solution. Add the dopant precursors to the titanium precursor: Slowly add the H3BO3 solution to the TTIP solution while stirring vigorously. Next, add the NH3.H2O solution dropwise to the mixture while stirring. The solution will turn milky white. Age the mixture: Keep the mixture stirring for 2-3 hours to allow the reaction to occur. Heat the mixture: Transfer the mixture to a Teflon-lined autoclave and heat it at 180°C for 12 hours. This will result in the formation of the TiO2 photocatalyst doped with Boron and Nitrogen. Wash and dry the photocatalyst: Once the reaction is complete, wash the photocatalyst with deionized water and ethanol to remove any impurities. Dry the photocatalyst at 80°C for 2-3 hours. Characterize the photocatalyst: Use techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS) to characterize the synthesized photocatalyst.
Synthesizing TiO2 photocatalysts by doping with Boron and Nitrogen from H3BO3 and ammonia solution is a well-established research topic. Here is a general procedure that you can follow:
Note: The above procedure is a general guideline and may need to be modified depending on the specific requirements of your research.
Best of luck with your research
