• Abstract:

  Triclinic CuWO4 structure

  particles were deposited onto transparent

  conducting glass electrodes to prepare porous

  photoelectrode with 1.0 cm2 of area, which was

  then used as photocatalysts for Rhodamine

  B (RhB) degradation. After 165 min under

  polychromatic irradiation with the solar simulator,

  the CuWO4 porous film promoted 35.4% of RhB

  removal. Superior efficiency was reached when

  CuWO4 photoelectrode was biased at + 0.7

  V, with RhB removal corresponded to 45.7%.

  Applying potential bias on electrode minimizes

  the recombination of photogenerated charge

  carriers, resulting in higher performance for

  organic pollutant degradation.
