Abstract
The present disclosure relates to constructs and methods of use thereof for improving NOx reduction in air. In particular, it has been found that improvements in NOx reduction are achieved when a photocatalytic, transparent or translucent titanium dioxide sol formulation is provided as a layer over a white surface or like surface that provides high reflection of incident light. The surface may be the surface of an underlying base structure or an applied layer, such as a paint. The base to which the layer(s) is applied can be a structure that is located where NOx concentration in the atmosphere is particularly high, such as near a roadway or other areas subject to significant vehicular traffic.
