Title
(EN) A SYSTEM AND METHOD USING PHOTOCHEMICAL OXYGEN STORAGE AND RELEASE
(FR) SYSTÈME ET PROCÉDÉ FAISANT APPEL AU STOCKAGE ET À LA LIBÉRATION PHOTOCHIMIQUE D'OXYGÈNE
Abstract
(EN)
Disclosed herein is a method for converting light energy into mechanical energy and/or oxygen storage, purification, isolation, concentration, and/or removed. The method may comprise exposing a mixture of a polycyclic aromatic compound and a photosensitizer to oxygen and light to form an endoperoxide, and decomposing the endoperoxide to reform the polycyclic aromatic compound and oxygen. The polycyclic aromatic compound may be a naphthalene compound or anthracene compound and/or may have a formula (I).
(FR)
L'invention concerne un procédé pour la conversion de l'énergie lumineuse en énergie mécanique et/ou le stockage, la purification, l'isolement, la concentration et/ou l'élimination de l'oxygène. Le procédé peut consister à exposer un mélange d'un composé aromatique polycyclique et d'un photosensibilisateur à de l'oxygène et à de la lumière pour former un endoperoxyde, et à décomposer l'endoperoxyde pour reformer le composé aromatique polycyclique et de l'oxygène. Le composé aromatique polycyclique peut être un composé naphtalène ou un composé anthracène et/ou peut avoir une formule (I).
