Key role of hydrochar in heterogeneous photocatalytic degradation of sulfamethoxazole using Ag₃PO₄-based photocatalysts.

ABSTRACT: To overcome the practical application limitations of Ag₃PO₄ such as photocorrosion and relatively low efficiency of photogenerated carrier seperation, Ag₃PO₄ particles were loaded onto hydrochar. The particles in the composite had a smaller crystallite size and different phase structure with more edges than pure Ag₃PO₄ particles. The as-prepared composite catalyst exhibited a different photocatalytic performance for sulfamethoxazole (SMX) degradation when varying the mass ratio of hydrochar and Ag₃PO₄. In addition to higher SMX degradation efficiency, the composite exhibited much higher TOC degradation efficiency, recycling stability, and less-toxic intermediate production. The composites enhanced visib
