Photosensitive properties of Molybdenum Disulphide

[Nikhil Rajagopalan]

Dear Experts,

I am studying about a Stanford University innovation, using Molybdenum Disulphide and solar radiation to disinfect water at a very quick rate. I am unable to find details about photo sensitive properties of Molybdenum Disulphide. What is the work function of molybdenum disulphide, how does it change with its thickness. I would be glad if I could find any resource which could guide me through the reactions and how the purification is done.
I have attached an image of the water purifying device here.
Thank you.

Of all the co-authors, Professor Alexandria Boehm might be the most approachable for advice and insight. aboehm@stanford.edu
