hi

  any one can give the details about laboratory scale test of photocatlytic properties evaluation of TiO2. I want to buy photocatlytic equipments. please give information regading this

                 thanks

howdy

 

I have not heard of anything for sale but it might be out there. You might investigate the petrochemical refining indistry.  They use alot of catalysts and I am sure they have methods to evaluate their efficiencies and other properties.  No reason you could not adapt one of their tests for your work.

You might pass a solution sensitive to the catalytic action over a coated plate and measure the before and after change.  The effect is probably subtle so you might recirculate the solution over the coating for some period of time.  Different wavelenghts of light, temeprature, pressure, etc.

 thank you very much for ur valuable information regading the test but actually some of the peoples they are evaluating the photocatalytic properties of TiO2 in diffenerent form like powders, thin films and rods useing a  photocatalytic reator

I think most people build their own reactors. It should not be complicated. The basic parts is a Xeno Lamp, a glass beaker, and maybe a quartz cover. You can check the literatures for the illustrations.

As long as you build the reactor, you can use TiO2 with any form for the test. Just place your sample in the solution and illuminate it with the UV-light. Check the concentration of some species before and after exposure. You will get what you want.

There is some instructions in the following paper.

H. Park, W. Choi, J.Phys.Chem. B 2004,108,4086.

I saw more detailed instructions before, but don't remember what was the paper. I suggest to check the experiments part of the papers that you can find, and you should be able to get what you need.
