Why the absorption band edge of tio2/cnts nanocomposites shift towards red light in DRS? Please explain

Mixing of SWCNT and MWCNT with TiO2 and doping F into TiO2 cause an extension of the absorption towards the red shift in the spectra. This extension for F-TiO2, F-TiO2/MWCNT and F-TiO2/SWCNT on...

Hello, H2O2 is oxidant agent which caused of generating a hydroxyl radical, the last is regarded as a power which used to start a photo reaction.

But the photosensitizer mostly is color organic compound (i.e. dye), that needed to suitable level of energy to inject her electron to photosemiconductor in order to increase the efficiency of reaction.Please, find attachment file....

Ramin Nasiri

thanks a lot

what is the common photosensitizer for photodegradation by tio2?

Any dyes that colour ranges betweem red degrees to pink ...and orange are best.
