Nanophotocatalytic synergistic degradation of antibiotics and microplastics: Mechanisms, material design, and environmental applications
This review examines how microplastics and antibiotics interact in water during photocatalytic treatment, finding that microplastics can both help (by shuttling electrons) and hinder (by shielding light or hosting biofilms) the degradation process, depending on conditions. Aged microplastics — which have more surface oxygen groups — adsorb more antibiotics, making them tougher composite targets for treatment systems. Understanding these interactions is essential for designing water purification systems that can handle the combined pollution reality of modern waterways.
