other hand, the additional O 1 s peak having the binding energy at 531.6 eV originated from the presence of –OH group or water molecule on the surface of WO 3 /Bi 3 O 4 Cl composite photocatalyst. This indicates that the tungsten oxide present on the

can be easily decomposed even at 25 °C [ 29 ], so it is difficult to form homogeneous phase at the absence of ionic liquid. Therefore, we propose that ionic liquid can coordinate to tungsten, and this coordination stabilized the catalytic system. On
