During November:- In case of photochemical method I prepared 4 different titanium dioxide substares and determined its influance on Ag nanoparticles formation. Ony for substrate annealed for 2h at 500 Celcsius the particles ware found.
- I was also adsorbing 100nm particles from commerial sollution( Ag cont. 20ppm , Zeta - 50 -V) and 50 -100nm particles solution from ICSP PAS ( Ag cont. 300ppm, Zeta - 30mV).
Larger particles covered abuot 4% of sample surface within 4 hour of deposition while smaller about 15 % quicker than 15minutes.
It means that concentration can be the most important parameter
