ABSTRACT=<p>In this study, novel two-dimensional (2D) g-C<sub>3</sub>N<sub>4</sub>@BiOCl/Bi<sub>12</sub>O<sub>17</sub>Cl<sub>2</sub> composites have been fabricated through a facile deposition-precipitation process. The as-prepared photocatalysts were characterized by XRD, SEM, TEM, XPS, UV-vis DRS, PL, Photocurrent, EIS, ESR, and N<sub>2</sub> adsorption-desorption. The photocatalytic activities were investigated through NO removal test in gas under visible light irradiation (λ &gt; 420 nm). The g-C<sub>3</sub>N<sub>4</sub>@BiOCl/Bi<sub>12</sub>O<sub>17</sub>Cl<sub>2</sub> composites exhibit enhanced visible light absorption and photo-induced electron-hole separation efficiency, compared with pristine g-C<sub>3</sub>N<sub>4</sub> and BiOCl/Bi<sub>12</sub>O<sub>17</sub>Cl<sub>2</sub>. The intimated contact interfaces between g-C<sub>3</sub>N<sub>4</sub> and BiOCl/Bi<sub>12</sub>O<sub>17</sub>Cl<sub>2</sub> nanosheets are responsible for the more efficient photochemical interactions. The present work provides a new direction to develop a class of ternary g-C<sub>3</sub>N<sub>4</sub>-based visible-light-driven photocatalysts for environmental purification.</p>
