Abstract
Three types of photocatalytic NO removal reaction including photo-assisted selective catalytic reduction (photo-SCR), photo-oxidation and photo-decomposition, were designated in the flue gas under elevated temperatures. The reliability of reaction pathways is supported by the excellent agreement of the change in the thermodynamic properties of individual catalytic reactions. The presence of O2 could further effectively improve the photocatalytic activity at the low reaction temperature. However, an excess consumption of both O2 and C4H10 was recognized by oxidation of C4H10 at the higher reaction temperature, resulting in the drop of the NO removal. This study provides the basis for designing the photocatalytic removal of NO with a hydrocarbon in the flue gas. ? 2016 Elsevier B.V. All rights reserved.
