This study explores the development and performance of photocatalytic cementitious composites modified with nano-TiO2 to address urban air quality sustainability challenges. Nine mortar series were prepared, incorporating binders varying carbon footprints mass contents across different series. The interplay between fundamental (abrasion resistance) functional (air purification efficiency) properties composites’ surfaces interfaces was investigated. removal airborne pollutants, specifically nitrogen oxides (NOx) ozone (O3), evaluated under simulated environmental conditions. variations in binder composition influenced overall initial footprint efficiency. assessment revealed a possible net decrease emissions over life cycle composite due (greenhouse gas) its precursor—NOx, highlighting potential for dual benefits an environment, emphasizing critical role surface interface engineering achieving carbon-negative composites.
