Photocatalytic degradation is a promising approach for tackling insecticide pollution, such as imidacloprid (IMI), but it faces challenges including low efficiency, long treatment times, and limited mineralization. Herein, we report a method utilizing carboxymethyl cellulose (CMC) macromolecules to regulate the growth of bismuth oxychloride (BiOCl) and synthesize ultra-thin BiOCl nanosheets (UT- BiOCl) for the photocatalytic removal of IMI. UT-BiOCl can photocatalytically degrade 99.9 % of IMI within 80 min. The photocatalytic degradation rate of IMI by UT- BiOCl was 2.4 times that of BiOCl. M...
