Conversion of VOC-derived CO into sustainable products with a natural magnetic alginate composite.

In this study, we developed a sustainable nanocatalyst, AXFe, by functionalizing magnetite nanoparticles with an alginate-xanthine conjugate (AX). This hybrid material combines magnetite's adsorption and photocatalytic properties with the CO fixation capabilities of alginate and xanthine. AXFe exhibited exceptional performance in the photocatalytic mineralization of toluene under simulated solar irradiation, achieving a 61.
