Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Photocatalysis has emerged as a promising method for industrial sewage elimination. The main bottleneck of this process is the development of an efficient, stable, and cost‐effective catalyst that can oxidize pollution under visible light. Herein, surface disorders and Bi nanoparticles are successfully introduced into BiOCl<italic>_x</italic>I_{1−<italic>x</italic>} nanosheets using low‐cost NaBH₄ as a reductant in a liquid‐phase environment. Benefiting from the enhanced charge separation, transfer, and donor density resulting from the formation of surface disorders, and Bi deposition as cocatalyst, the photocatalytic performance of the reductive BiOCl<italic>_x</italic>I_{1−<italic>x</italic>} nanosheets is fivefold higher than that of the untreated BiOCl<italic>_x</italic>I_{1−<italic>x</italic>} nanosheets for phenol degradation under visible light irradiation. Additionally, the reductive BiOCl<italic>_x</italic>I_{1−<italic>x</italic>} nanosheets have a superior stability after five cycles.</p> </abstract>
