Abstract

La presente divulgación se refiere a constructos y métodos de uso de los mismos para mejorar la reducción de NOx en el aire. En particular, se ha encontrado que las mejoras en la reducción de NOx se logran cuando se proporciona una formulación de sol de dióxido de titanio fotocatalítico, transparente o translúcido como una capa sobre una superficie blanca o superficie similar que proporcione alta reflexión de la luz incidente. La superficie puede ser la superficie de una estructura de base subyacente o una capa aplicada, tal como una pintura. La base en la cual se aplica(n) la(s) capa(s) puede ser una estructura que esté ubicada donde la concentración de NOx en la atmósfera sea particularmente alta, tal como cerca de una carretera u otras áreas sujetas a tráfico vehicular significativo.
