The efficacy of Co 3 O 4 loaded WO 3 sheets for the enhanced photocatalytic removal of 2,4,6-trichlorophenol in natural sunlight exposure.

•Nanostructured Co3O4 entities deposited at the surface of sheet-like WO3.•The composite formation consequences the mild variations in the bandgaps.•The surface existence of the Co3O4 promotes the photocatalytic activity.•The composites showed stability and retention of activity over a wide range of pH.•The addition of H2O2 promotes the removal process.
