A series of highly dispersed platinum-deposited porous g-C₃N₄ (Pt/pg-C₃N₄) were successfully fab-ricated by a simple in situ photoreduction strategy using chloroplatinic acid and porous g-C₃N₄ as precursors. Porous g-C₃N₄ was fabricated by a pretreatment strategy using melamine as a raw ma-terial. The morphology, porosity, phase, chemical structure, and optical and electronic properties of as-prepared Pt/pg-C₃N₄ were characterized. The photocatalytic activity of as-prepared Pt/pg-C₃N₄ was preliminarily evaluated by the degradation of aqueous azo dyes methyl orange under visible light irradiation. The as-prepared Pt/pg-C₃N₄ were further applied to the degradation and mineral-ization of aqueous 4-fluorophenol. The recyclability of Pt/pg-C₃N₄ was evaluated under four con-secutive photocatalytic runs.
