Description de la ressource pédagogique
Description (résumé)
The increasing CO2 level in the atmosphere is a global environmental problem; therefore, the development of efficient catalytic processes for CO2 reduction is a challenge. Heterogeneous photo-catalysis is an attractive technology for this purpose. Literature reports that formic acid, methanale, methanol and methane can be formed by photocatalytic reduction of CO2. In this contribution, it will be showed that the CO2 reduction products and their distribution depend on several factors like the kind of photocatalyst and the presence of water vapor [1]. Moreover, the coupling of different photo-catalyst (GaP/TiO2) and the use of nafion membranes as support of the catalyst can improve the photocatalytic performances [2,3]. In the case of photo-reduction performed in liquid-solid regime, the temperature and the pressure have a positive effect on the productivity. Finally, an investigation into the stability of C3N4 used as photo-catalyst for CO2 reduction will be discussed [4]. References [1] M. Bellardita, A. Di Paola, E. García-López, V. Loddo, G. Marcì, L.
