Wet air oxidation of paracetamol over precious metal/Ti mesh monolith catalyst
E-mail:
The catalytic wet oxidation of paracetamol (PAR) was tested with Pt, Ru, Ir containing Ti monoliths measuring COD, TOC and TN conversion and compared with that of the non-catalytic reaction. The decrease of PAR concentration during reaction was followed by UV-vis spectrometry also. The catalysts were characterized by XPS, PGAA, TPR and SEM-EDX. The monometallic Pt and Ru/Ti catalysts were the most active, even below 150 °C. RuO2/Ti had the highest specific activity. After 100 h reaction time the Pt loss was 23%, while the RuO2/Ti kept its Ru content. The RuO2/TiO2 composite formation explains the highest activity and stability.
