C‐doped into the BiOBr is a big challenge because unique lattice structure. Here, using sodium alginate (SA) as the structure‐directing agent and C source, the C‐doped BiOBr micron‐flower (BiOBr‐SA) was in‐situ synthesized with KBr and Bi(NO 3 ) 3 with hydrothermal, and characterized by XRD, SEM, XPS, BET and DRS. It was found that SA could control morphology of BiOBr‐SA as it contains carboxylate groups. Meanwhile, C−Bi bonds were formed in nanosheets, and further self‐assembled into BiOBr‐SA micron‐flower. Using BiOBr‐SA as photocatalyst for degradation of antibiotic and dye, the removal rate of tetracycline got to 88.7%.
