The high carrier recombination rate and serious photocorrosion of Ag₃PO₄ greatly restrict its photocatalytic application. Here, we fabricated an Ag₃PO₄/Ti₃C₂ Schottky catalyst and found that Ti₃C₂ can greatly enhanced the catalytic activity and stability of Ag₃PO₄. This arises from: (i) the abundant surface hydrophilic functional groups of Ti₃C₂ construct strong interfacial contact with Ag₃PO₄, which facilitate the separation of carriers; (ii) the strong redox reactivity of surface Ti sites promote multiple electron reduction reactions to induce more radical dotOH production; and (iii) a Schottky junction formed at Ag₃PO₄-Ti₃C₂ interface timely transfer electrons to Ti₃C₂ surface by built-in electric field, inhibiting the photocossion of Ag₃PO₄ caused by photogeneration electrons. Consequently, Ag₃PO₄/Ti₃C₂ exhibited excellent photocatalytic activity and stability for the degradation of organic pollutants. Especially, the …
