Bismuth oxychloride ultrathin nanoplates (BiOCl‐UTNs) are highly active, but their preparation are limited to closed‐vessel hydrothermal and solvothermal techniques at high temperatures (110–180 °C). Here we report a straightforward poly(sodium 4‐styrenesulfonate) (PSS)‐mediated route for the large‐scale synthesis of BiOCl‐UTNs at room‐temperature. In an open vessel, 6.15 g of BiOCl‐UTNs with 3–5 nm thickness, and planar dimensions of 30–50 nm were produced. The strong electrostatic interaction between PSS and [Bi 2 O 2 ] 2+ layers inhibited the growth rate of BiOCl nanoplates along <001> direction, and Na + ions governed the electrolyte sedimentation to produce BiOCl‐UTNs. The resulting BiOCl‐UTNs exhibited high photocatalytic activity for the degradation of antibiotics and organic dyes because of their large specific surface area, increased light absorption ability, and fast separation and transfer efficiency of the photoexcited charge carriers.
