Utilization　of　solar　heat　radiation　into　chemical　energy　is　attributed　to　semiconductor　photocatalyst　under　sunlight　perspective　considered　as　a　reversing　inspired　approach　that　exacerbates　the　environmental　problems.　Recently,　our　group　indicates　graphitic　carbon　nitride　(g-CN)　by　a　progressive　molecular　aggregation　co-polymerization　process　that　propagated　with　a　nanoscopic　organic　conjugated　heterocyclic　monomer　to　enhance　its　photocatalytic　activity.　This　work　aims　to　present　a　facile　induced　co-condensation　technique　and　used　2,　6-Furandicarboxylic　acid　(FA)　monomer　as　demonstrator　within　g-CN　that　boosting　the　photocatalytic　properties　under　solar　energy　driven　caused　the　reduction　of　water.　The　as-prepared　samples　were　demonstrated　for　various　characterizations　along　with　computational　evaluation　of　pure　and　doped　g-CN.　The　result　signifying　the　integration　of　organic　FA　monomer　in　the　triazine　core　shell　of　g-CN　restoring　a　substantial　delocalization　in　its　π-conjugated　system.　Meanwhile,　after　this　alternation,　an　identifiable　undulation　occurred　in　the　surface　area,　electronic　structure,　calculated　band　gap,　chemical　composition　analysis　of　g-CN,　and　also　improved　its　electronic　generation　process　under　the　visible　light　radiance.　Besides,　this　unrepeatable　integrity　of　FA　co-monomer　with　ing-CN　matrix　considerably　enhanced　the　photocatalytic　activity　toward　Godspeed　and　as　such,　the　superior　photocatalyst　CN/FA12.0　stimulated　a　tremendous　photocatalytic　activity　of　water　reduction　with　10.6　enhanced　catalytic　performances　as　a　contrast　of　pristine　sample　respectively.　©　2020　Elsevier　B.V.
