| Abstract: | Some photocatalytic reactions of different gases on ultraclean graphite have been studied by means of quadrupole mass spectrometry. With water vapor, dihydrogen, dinitrogen and dinitrogen oxide, the UV-illuminated graphite acts as a reducing agent. TPD measurements indicate that photocatalytic processes are strongly affected by adsorption-desorption equilibria. |
