pH effect on the photocatalytic oxidation of butan-2-ol over naked titanium dioxide

الملخص EN

The effect of pH on the photocatalytic oxidation of butan-2-ol over naked titanium dioxide has been investigated.

The apparatus which is used in the photocatalytic reaction has a precies temperature control which gives a high precision for the reaction.

Spectrophotometric method was used in the determination of amount of the product formed, this method is based on the formation of 2,4–dinitrophenyl hydrazone of the produced carbonyl product, followed by the addition of alcoholic potassium hydroxide to give a wine colour which is measured by spectrophotometric method.

The measurements were done at 298 K using different buffer solutions, and irradiation with ultraviolet light from mercury vapour lamp (150) Watt.
