Abstract The oxidation of C2H4 deposits on polycrystalline Pt when exposed to consecutive O2 and H2 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 O2/H2 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.
