The photocatalytic process is based on the own nature’s decontamination process...
benefits of photocatalytic :-
•••••••••••••••••••••••••••••••••••••••••••
Environmental Benefit of Photocatalytic Coatings, such as titanium dioxide (TiO2), are suitable for manifold applications due to their potential application for decomposing a great variety of substances and materials in the air, Photocatalytic active coating systems are able to reduce environmental contaminations and to clear surface of various material.

Both the technological and economic importance of photocatalysis has increased considerably over the past decade. Improvements in performance have been strongly correlated to advances in nanotechnology. A variety of applications ranging from anti‐fogging, anti‐microbial and self‐cleaning surfaces, through to water and air purification and solar induced hydrogen production, have been developed and many of these have made their way into commercial products.........................
I don't know the disadvantages....
