Decomposition of nitrophenol by wet oxidation in the presence of noble metal catalysts

Abstract

Wet oxidative decomposition of nitrophenol, one of water pollutants, was studied at 150 and 200°C in a stirred autoclave. Nitrophenol was decomposed to give lower-molecular compounds, including formic and acetic acids. Catalysts accelerated the decomposition. The removal of TOC as a measure of the decomposition was 70% after 30 min at 150°C in the presence of a platinum catalyst supported on titania, while 0% in the absence of catalysts.
