Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 2,   Pages 120-126 doi: 10.1007/s11705-009-0232-3

Abstract: Photocatalytic reduction of CO on TiO and Cu/TiO photocatalysts was studied by in situ diffuse reflectanceof reaction intermediates were found on the IR spectra, which were due to the slow photocatalytic CO reductionPhotogenerated electrons merge with H ions to form H atoms, which progressively reduce CO to form formicsignificantly increases the amount of formaldehyde and dioxymethylene, thus promotes the photoactivity of CO reductionA possible mechanism of the photocatalytic CO reduction is proposed based on these intermediates and
