摘要/描述

The degeneration of energy level ofα, β, γ, δ-tetrahydroxylphenylporphyrin(THPP)and red shift of the photovoltage peaks of THPP are observed as the size of nano-TiO2 decreasing using surface photovoltage(SPV)technique, while that ofα, β, γ, δ-tetraphenylporphyrin(TPP)have little change. The reason for that is the existence of hydroxyls of THPP, which interact with the surface of nano-TiO2. This difference was also demonstrated by IR spectrum.
