PHOTOCATALYTICAL REDUCTION PROCESS OF CARBON DIOXIDE IN THE PRESENCE OF AN EXTERNAL ELECTRIC FIELD

摘要

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