“…1,2 Bandgap excitation by UV light led to the formation of methane and methanol as products. Most semiconductor studies were conducted with aqueous suspensions of colloidal particles of TiO 2 , ZnS, ZnSe, CdSe, etc., often surface-modified to enhance efficiency, selectivity, or wavelength response.…”

The 266 nm light-induced reaction of CO 2 and H 2 O gas mixtures (including isotopic modifications 13 CO 2 , C 18 O 2 , and D 2 O) in framework TiMCM-41 silicate sieve was monitored by in-situ FT-IR spectroscopy at room temperature. Carbon monoxide gas was observed as the sole product by infrared, and the growth was found to depend linearly on the photolysis laser power. H 2 O was confirmed as stoichiometric electron donor. The work establishes CO as the single photon, 2-electron transfer product of CO 2 photoreduction by H 2 O at framework Ti centers for the first time. O 2 was detected as co-product by mass spectrometric analysis of the photolysis gas mixture. These results are explained by single UV photon-induced splitting of CO 2 by H 2 O to CO and surface OH radical.

“…In particular, there are only a few reports on the photochemical reduction ofC02, and most ofthe processes are very inefficient (12). Recent CO2 reduction experiments involved irradiation of aqueous solutions of metal ions (12)(13)(14)(15) or of organic dyes (16), irradiation of semiconductor crystals (17) or powders (18), and photoelectrochemical processes (19)(20)(21).…”

Contributed by Jean-Marie P. Lehn, October 8, 1981 ABSTRACT Visible light irradiation of solutions of Ru(2,2'-bipyridine)2+, cobalt(ll) chloride, and carbon dioxide in acetonitrile/water/triethylamine generates simultaneously carbon monoxide and hydrogen. The reaction involves photoinduced reduction of CO2 and H20, triethylamine serving as electron donor in the Ru(2,2'-bipyridine)2+/Co2+ system. The amount of gas (CO

“…For example, Hemminger et al 93 reported that methane was directly obtained from gaseous water and CO2 adsorbed on strontium titanate (111) crystals that were in contact with platinum foils by illumination with light of energy greater than the band gap of the semiconductor or by heating to 420 K in the dark; surface Ti3+ ions were proposed to act as a catalyst.…”
