Photocatalytic　cementitious　materials　(PCMs)　are　a　promising　material　for　air　purification　at　ambient　conditions.　Herein,　polymeric　carbon　nitride　(PCN),　a　material　with　high　chemical　and　thermal　stability　that　is　responsive　to　visible　light,　was　employed　for　the　fabrication　of　PCMs　with　the　assistance　of　two　adhesives　(i.e.,　acrylic　latex　and　waterglass).　The　effect　of　the　adhesives　on　the　photocatalytic　removal　of　nitrogen　oxides　(NOx)　and　their　stability　over　the　PCN-coated　PCMs　was　studied　under　various　environmental　conditions.　Experimental　results　indicated　that　the　waterglass-based　PCMs　outperformed　the　acrylic　latex-based　PCMs　in　terms　of　the　photocatalytic　NOx　removal　under　visible　light　irradiation　and　stability　in　the　peeling　and　washing　trials.　The　relative　humidity　had　beneficial　effects　on　the　NOx　removal　efficiency　for　the　acrylic　latex　and　deleterious　effects　on　the　waterglass　incorporated　PCMs,　due　to　their　distinct　surface　wettability.　The　ambient　temperature,　initial　nitrogen　monoxide　(NO)　concentration,　and　light　intensity　had　a　positive　impact　on　the　NOx　removal　efficiency　for　the　as-prepared　PCMs.　©　2021　Elsevier　Ltd
