Although carried out in air, UV photolysis of Fe-(CO)[sub 5] physisorbed onto porous Vycor glass yields elemental iron and iron oxide. Moessbauer spectra and the X-ray absorption pre-edge feature analyses show that after photolysis, 53-60% of the iron deposited in the glass is Fe[sup 0], and the remainder, principally Fe[sub 2]O[sub 3]. Heating in air to 650[degrees]C and consolidating the glass result in some oxidation, but 40-49% of the iron deposited photochemically remains as Fe[sup 0].
