FTIR spectroscopy of hydrogen, carbon monoxide, and ...

03-12-2001 · Adsorption of dihydrogen, carbon monoxide and methane, and co-adsorption of H 2 /CO, H 2 /CH 4 and CO/CH 4 on zinc oxide was studied by means of Fourier transform infrared spectroscopy. Besides the already known dissociation of dihydrogen and molecular adsorption of CO, methane was found to be adsorbed molecularly on coordinatively unsaturated Zn 2+ ions.
