Visible-light-driven Z-scheme tungsten oxide/ silver phosphate/ coffee bean biochar photocatalyst for simultaneous degradation of ciprofloxacin and chlorpyrifos.

ABSTRACT: The integration of biochar as a solid-state electron mediator in Z-scheme photocatalytic systems represents a promising approach for the efficient degradation of organic contaminants. In this study, a novel magnetic Z-scheme photocatalyst, silver phosphate-tungsten oxide (Ag₃PO₄-WO₃)/coffee bean biochar composite (ABW-10), was synthesized via a hydrothermal method. Ag₃PO₄ and WO₃ were immobilized onto biochar layers to facilitate charge separation and enhance electron transfer under visible light irradiation. Morphological analysis confirmed a uniformly decorated biochar surface with well-dispersed nanoparticles, supporting efficient photocatalytic performance. Mott-Schottky plots revealed improved charge carrier dyna
