Solvent effect on the photocatalytic reduction of 4-nitrophenol in titanium dioxide suspensions

The selective photocatalytic reduction of 4-nitrophenol to 4-aminophenol in titanium dioxide suspensions prepared in aliphatic alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, i-butanol) was investigated. The photoreduction rate is significantly affected by the solvent parameters, suc...

Description
Summary:The selective photocatalytic reduction of 4-nitrophenol to 4-aminophenol in titanium dioxide suspensions prepared in aliphatic alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, i-butanol) was investigated. The photoreduction rate is significantly affected by the solvent parameters, such as viscosity, polarity, polarisability, and polarity/polarisability.
