Abstract

Abstract: The rate of photocatalytic decomposition of aqueous solutions of various organic car-boxylic acids with suspended Pt/TiO₂ powder was determinated and the inductive effect index of organic groups attached on the carboxylic group was calculated. It was found that the influence of the electron pulling ability of attached group on the decomposition of organic carboxylic acid is the dominating factor. A relation between the rate of photocatalytic decomposition and the molecular structure of the organic acid was observed.

Key words: photocatalytic decomposition. organic carboxylic decomposition, titanium oxide, inductive effect index
