Abstract

Layer double hydroxide, Zn2Cr-CO3, is implemented as photocatalytic additive for DeNOx building mortars. When this additive was prepared by the AMOST method (ZnCr-AMO), a high NOx removal efficiency was achieved (ENO = 67 %). ZnCr-AMO has been easily scaled and added to the cement-base mortars formulation in different percentages (0.5, 1 and 2 wt%) and submitted to the DeNOx photocatalytic test. The results showed that the DeNOx activities of mortars containing ZnCr-LDH and commercial TiO2 were quite similar, around 50 %, which is a very promising data for this new application of LDH in building materials.
