(a) Kinetics of Rhodamine B (RhB) adsorption onto the BiOCl/Bi₂WO₆ hybrids. (b) Removal of RhB solution (1 M) with time over the as-prepared samples: (i) BiOCl, (ii) BiOCl/Bi₂WO₆ hybrids and (iii) Bi₂WO₆. (c) The photocatalytic activity of the RhB solution with different concentrations over the BiOCl/ Bi₂WO₆ hybrids: 2 M, 3 M and 5 M, respectively. (d) The photocatalytic degradation of ciprofloxacin (CIP) solution by (ii) BiOCl/Bi₂WO₆ hybrids and (iii) Bi₂WO₆. (e) Reactive species trapping experiments and (f) Stability experiment of BiOCl/Bi₂WO₆ hybrids: RhB solution (2 M).
