METHOD OF PHOTOCATALYTIC CONVERSION BY TRANSFORMATION OF SOLAR IRRADIATION IN IRRADIATION SUITED TO ACTIVATION OF THE PHOTOCATALYST.

摘要

The present invention describes a process for conversion of at least one photocatalytic reagent in at least one product in the presence of a photocatalyst comprising the following steps: a) it provides a photocatalyst, b) is transformed into the solar radiation into electrical energy, said electrical energy being only be used directly in the step c), is stored in an electrical energy storage device, c) it provides a source of irradiation which emits at a nominal wave length at most 50 nm, less than the maximum wavelength absorbable by the photocatalyst and which produces an irradiation such that at least 50% by number of photons are absorbable by the photocatalyst, and then feeds said source of irradiation at least in part by the electrical energy produced and / or stored at step b), d) and then the photocatalytic of said reagent in the presence of the photocatalyst activated by said source of irradiation.
