Abstract Ag nanoparticles were uniformly attached to the surface of K0.3WO3 nanorods by the chemical reduction method. The photocatalytic performance and NIR shielding property of the nanocomposites could be regulated by changing the mass ratio of Ag to K0.3WO3. The NIR shielding ability of the nanocomposites was as high as 49.8%. The prepared K0.3WO3/Ag nanocomposites exhibited improved visible photocatalytic performance, resulting in an enhanced self-cleaning property of K0.3WO3/Ag films. The improvement in visible photocatalytic activity of the K0.3WO3/Ag nanocomposites could be attributed to the improved separation efficiency of photo-generated carriers. Furthermore, K0.3WO3/Ag coated glass can reduce the interior temperature of the heat box by 2.4 °C. Therefore, the integration of good visible light transmittance, superior visible photocatalytic self-cleaning property, and strong NIR shielding performance make K0.3WO3/Ag nanocomposites good candidates for smart window coatings.
