1. An article, the article comprising:

a surface; and

an antimicrobial coating disposed on the surface, the coating comprising a phosphorus-doped graphitic carbon nitride (g-C₃N₄) composition, the phosphorus-doped g-C₃N₄composition exhibiting one or more of phosphorus atom-containing tri-s-triazine units, tri-s-triazine units linked together with a phosphorus atom, and a phosphorous atom bound to nitrogen atoms and oriented toward a pore of the g-C₃N₄.
