Wet air oxidation of paracetamol over precious metal/Ti mesh monolith catalyst

[Display omitted] 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....

Summary:[Display omitted] 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 100h 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.
