METHOD FOR THE PHOTOCATALYTIC REDUCTION OF CARBON DIOXIDE IN THE PRESENCE OF AN EXTERNAL ELECTRIC FIELD

摘要

The invention relates to a method for the photocatalytic reduction of carbon dioxide carried out under irradiation in the liquid phase and/or in the gas phase using a photocatalyst in the presence of an external electric field, with the proviso that the photocatalyst is not in electric contact with the field-generating electrodes. Said method is carried out by bringing a feed containing CO2 and at least one sacrificial compound into contact with said photocatalyst, then by subjecting the photocatalyst to an external electric field and by irradiating the photocatalyst so as to reduce the CO2 and oxidize the sacrificial compound so as to produce an effluent containing at least part of the C1 or more C1-carbon molecules different from the CO2.
