▎ 摘　　要

NOVELTY - Graphene-like carbon nitride photocatalyst preparation involves adding deionized water to a crucible, adding urea and potassium phosphate heptahydrate to obtain a photocatalyst precursor, and then recrystallizing the obtained photocatalyst precursor to obtain recrystallized product. The obtained recrystallized product is heat-treated in a muffle furnace to obtain a graphene-like carbonitride carbon photocatalyst doped with potassium hexahydrate. USE - Method for preparing graphene-like carbon nitride photocatalyst doped with interlayer potassium hexahydrate. ADVANTAGE - The method prepares the graphene-like carbon nitride photocatalyst in a simple, cost-effective and eco-friendly manner with improved light absorption efficiency and visible light photocatalytic activity. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation depicting active radical detection of the graphene-like carbonitride carbon photocatalyst and pure phase graphene-carbon nitride photocatalyst doped with interlayers of potassium hexahydrate.
