A nano-sphere material of BiOCl with a high photocatalytic efficiency was prepared by a simple coprecipitation method at room temperature. The addition of organic carboxylic acid can cause BiOCl to form a seriously agglomerated nanosheet structure, and then gradually transform into an irregular nanomicrosphere structure assembled from nanosheets. Also, the micro-mesoporous structures are formed on the surface of BiOCl nanosheets due to the corrosive effect of organic acids, thus increasing the specific surface area of BiOCl materials and providing the more active sites for the adsorption of pollutants and photocatalysis. Among them, the specific surface area of BiOCl modified with tartaric acid (TA) and citric acid (CA) are 469.93 m2/g (BiOCl-TA) and 646.82 m2/g (BiOCl-CA), respectively, compared to that of pure BiOCl (106.90 m2/g). The photocatalytic degradation performance of the materials modified by organic carboxylic acid (i.e., BiOCl-TA and BiOCl-CA) enhances, and the degradation percentage of rhodamine B (RhB) (20 mg/L) in 30 min is 99.74%, which is greater than that of pure BiOCl (i.e., 14.83%).
