Environmental pollution from organic dyes in wastewater remains a critical global challenge. This study presents a novel of a "cotton floc-like" ZnO–BiOI hybrid material. By combining zinc oxide (ZnO) and bismuth oxyiodide (BiOI), we developed a heterostructure that significantly enhances photocatalytic activity under visible light . The unique morphology improves light absorption and facilitates the separation of photo-generated charge carriers. Our findings demonstrate rapid degradation of organic pollutants, high stability, and ease of recovery from aqueous solutions. 1. Introduction

: A rapid one-step hydrothermal or solvothermal method was employed to produce the ZnO–BiOI composite. 124272
: The degradation of organic pollutants (e.g., methylene blue or methyl orange) was monitored under visible light irradiation. 3. Results and Discussion
: The ZnO–BiOI heterostructure exhibited a significant redshift in light absorption compared to pure ZnO, confirming its efficacy under visible light. Introduction It looks like there's no response available
: The cotton floc-like structure provides a high surface area, which maximizes the contact between the catalyst and pollutants.
: The formation of a p-n heterojunction creates an internal electric field that drives electrons and holes in opposite directions, reducing recombination rates. This synergy leads to the production of reactive oxygen species (ROS) like hydroxyl radicals ( ) and superoxide radicals ( ), which Mineralize the organic dyes. 4.
