Catalytic wet oxidation of N,N-dimethylformamide was tested in designed experiments without and with Ru-Ir on Ti mesh monolith catalysts. The rate and selectivity of the reactions were compared with the usual DOE evaluation of the data. The commercial catalyst and its reduced version, before and after usage 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 the precious metal loss was insignificant. The active surface can have dual nature, containing both oxide and metallic sites independently from the starting state of the catalysts.
