Abstract

Abstract : Novel Cs x WO3 /ZnO nanocomposites were developed to achieve the multifunction of heat insulation, toxic gas photodecomposition and harmful UV light blocking. Abstract : A novel Cs x WO3 /ZnO smart coating was proposed to achieve multiple functions, such as heat insulation, photodecomposition of toxic NO gas, blocking of harmful UV light, etc . In this composite coating, Cs x WO3 nanorods were used as a NIR and UV light shielding material while ZnO nanoparticles were utilized as a photocatalyst and a material to enhance visible light transmittance and block UV light. When the mass ratio of Cs x WO3 /ZnO was 1, the composite coating possessed a very good visible light transmittance of over 80% and an excellent UV-shielding ability. This novel coating showed heat insulation that is superior to the ITO coating and photocatalytic decontamination of NO gas that is superior to the standard TiO2 (P25). The proposed Cs x WO3 /ZnO smart coating is a promising material not only for energy saving but also for environmental cleanup.
