employing uncomplicated and value-efficient experimental disorders, Sang et al. described the fabrication of nanoflower-like Bi2O3/Bi2S3 heterojunctions by using a one-step hydrothermal technique [97]. In the photocatalytic elimination of RhB and Cr(VI) beneath obvious-gentle irradiation, the photocatalytic action of the Bi2O3/Bi2S3 heterojunctions
