The oxidation of C2H4 deposits on polycrystalline Pt when exposed to consecutive O-2 and H-2 pulses at room temperature has been investigated in a long (L=36 mm), shallow (d=600-700 nm) micromachined glass-SiO2-Pt channel. Hydrogen-induced CO2 formation from species accumulated on the Pt surface was observed. Frequent switching of the O-2/H-2 exposure pulses was found to increase the efficiency of the oxidation of the carbonaceous deposits markedly. The observations may be of general interest for the regeneration of contaminated catalysts.
