Herein, the formation of carbon monoxide as a harmful product upon Catalytic Wet Peroxide Oxidation process is studied in presence different solid catalysts: an iron supported activated catalyst, metal-free catalyst based on Graphene Nanoplatelets, and 1.6 wt.% Fe containing Cr2AlC MAX phase catalyst. The CWPO performance evolution gas effluent have been compared to that obtained conventional F...

the present state-of-the-art in gas detection does not allow the precise titration of a combustible gas in air with a single catalytic sensor, because the signal depends also on other parameters than the oxidation of the gas. It is why the catalytic transducers always consist of both a detector and a compensating element. We present here a process which permits the avoidance of the compensating...

vanadium phosphorus oxides (vpo) has been applied as a heterogeneous catalyst in gas phase oxidation reactions and its application is very limited in liquid phase. in this study a series of cobalt-doped vanadium phosphorus oxides (vpo-co) catalysts with different loading of co (0.01-1.0 mol ratio of co/v) were prepared. oxidation of benzyl alcohol was studied in the liquid phase over vpo and vp...

An automated flow micropacked bed catalytic reactor platform was developed to conduct pre-planned experiments for rapid screening of kinetic models. The microreactor fabricated using photolithography and deep reactive ion etching a silicon wafer, with reaction channel width depth 2 mm 420 μm respectively. It packed ca. 10 mg 5 wt. % Pd/Al2O3 catalyst perform methane combustion, which the select...

Different lanthanide (Ln)-doped cerium oxides (Ce0.5Ln0.5O1.75, where Ln: Gd, La, Pr, Nd, Sm) were loaded with Cu (20 wt. %) and used as catalysts for the oxidation of ethyl acetate (EtOAc), a common volatile organic compound (VOC). For comparison, both Cu-free (Ce-Ln) and supported Cu (Cu/Ce-Ln) samples were characterized by N₂ adsorption at -196 °C, scanning/transmission electron microscopy, ...

Control and tunability of the catalytic oxidation of CO by gold clusters deposited on MgO surfaces grown on molybdenum, Mo(100), to various thicknesses are explored through temperature-programmed reaction measurements on mass-selected 20-atom gold clusters and via first-principles density functional theory calculations. Au(20) was chosen because in the gas phase it is characterized as an extrao...
