The catalytic wet oxidation of paracetamol (PAR) was tested with Pt, Ru, Ir containing Ti monolithsmeasuring COD, TOC and TN conversion and compared with that of the non-catalytic reaction. Thedecrease of PAR concentration during reaction was followed by UV–vis spectrometry also. The catalystswere characterized by XPS, PGAA, TPR and SEM-EDX. The monometallic Pt and Ru/Ti catalysts were themost active, even below 150 C. RuO2/Ti had the highest specific activity. After 100 h reaction time the Ptloss was 23%, while the RuO2/Ti kept its Ru content. The RuO2/TiO2 composite formation explains thehighest activity and stability.
