The catalytic partial oxidation of methane (CPO) over flame-made 2.5%Rh–2.5%Pt/Al2O3 and 2.5%Rh/Al2O3 in 6%CH4/3%O2/He shows the potential of in situ studies using miniaturized fixed-bed reactors, the importance of spatially resolved studies and it

During the catalytic partial oxidation (CPO) of methane to hydrogen and carbon monoxide distinct spatial changes of the catalyst structure in a microreactor containing a fixed-bed of 2.5 wt% Rh/Al 2 O 3 were observed depending on temperature and spac

Tremendous changes of the structure of Rh particles occurred during partial methane oxidation to hydrogen and carbon monoxide over a 2.5 wt % Rh/Al(2)O(3) catalyst upon ignition of the catalytic reaction. Furthermore, near the ignition temperature a

Peroxynitrous acid was reduced by cathodic linear sweep voltammetry at a gold electrode and by iodide at pH 3.2 and 5.6. The cathodic reduction wave was identified by measuring its decay in time, which was the same as observed by optical spectroscopy
