Presently,　we　engineered　carbon　nitride　CN　by　specialized　molecular　doping　with　cyanuric　acid　(CA)　to　improve　the　metallic,　electronic　and　photocatalytic　assets　under　solar　energy.　The　integration　of　CA　monomer　in　CN　significantly　improve　the　efficient　charge　mobility　and　give　a　robust　casing　due　to　carbon/sulfur　ingredients.　Findings　confirm　that　the　incorporation　of　CA　in　the　heptazine　framework　of　CN　introduce　a　remarkable　polarization　in　its　conjugated　state　and　consequently　illustrate　an　obvious　variability　in　its　surface　area,　electronic　structure,　band　distance　and　chemical　composition.　Moreover,　this　exceptional　consistency　significantly　enhances　the　photocatalytic　operation　toward　sustainability　and　therefore　the　superior　UCN1:1　sample　illustrated　a　momentous　photocatalytic　activity　of　H-2　evolution　as　well　of　RhB　pollutant　photodegradation.
