Abstract
L'invention décrit un procédé de réduction photocatalytique du dioxyde de carbone effectué en phase liquide et/ou en phase gazeuse sous irradiation mettant en œuvre un photocatalyseur comprenant un support et des nanoparticules de sulfure de molybdène ou de sulfure de tungstène présentant une bande interdite supérieure à 2,3 eV, ledit photocatalyseur étant préparé par imprégnation en milieu fondu suivie d’une sulfuration. Ledit procédé est effectué en mettant en contact une charge contenant le CO2 et au moins un composé sacrificiel avec ledit photocatalyseur, puis en irradiant le photocatalyseur de manière à réduire le CO2 et oxyder le composé sacrificiel de manière à produire un effluent contenant au moins en partie des molécules carbonées en C1 ou plus, différentes du CO2.
