Wet air oxidation of paracetamol over precious metal/Ti mesh monolith catalyst
Erika Szabados,Gyuri Sági,Ferenc Somodi,Boglárka Maróti,Dávid Srankó,Antal Tungler 한국공업화학회 2017 Journal of Industrial and Engineering Chemistry Vol.46 No.-
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.

Catalytic wet oxidation of N,N-dimethylformamide was tested in designed experiments without andwith Ru–Ir on Ti mesh monolith catalysts. The rate and selectivity of the reactions were compared withthe usual DOE evaluation of the data. The commercial catalyst and its reduced version, before and afterusage were characterized with PGAA, TPR, SEM with EDX, XPS techniques. The catalytic reaction rates were significantly higher than the thermal one. During 55 h usage theprecious metal loss was insignificant. The active surface can have dual nature, containing both oxide and metallic sites independently fromthe starting state of the catalysts.
Carbon dioxide reforming of methane over Ni–In/SiO2 catalyst without coke formation

It was found that coke formation on Ni/SiO2, used in dry reforming of methane, can be eliminatedcompletely by addition of indium to the catalyst. The interaction of the two metals was suggested by theresults of TPR, CO-TPD and XPS measurements. The presence and uniform distribution of NiIn and Ni2Inalloy nanoparticles after reduction at 700 C of the calcined catalyst was shown by HAADF-STEM, HRTEMand EDX analysis. The indium atoms dilute the nickel surface inhibiting the formation of multiplebondedcarbon species thereby hindering the development of carbon nanostructures on the catalystsurface during dry reforming.
