In this study, boron oxide (B2O3) powder has been
synthesized by the pyrolysis of polyvinyl borate precursor in air. For this
purpose, polyvinyl borate precursor was synthesized through the condensation
reaction of polyvinyl alcohol and boric acid, and then the polymeric precursor
was pyrolyzed at 500°C. The as-prepared B2O3
particles were doped with iron (Fe) ions using the wet impregnation method. The photocatalytic activity of both undoped B2O3
and iron doped B2O3 (Fe-B2O3)
powders was studied by investigating the degradation of the model dye, methylene
blue, under UV light irradiation. It was pointed out that iron doped B2O3
powder exhibited enhanced photocatalytic activity compared to undoped one. In
addition, various techniques of characterization such as FTIR, XRD, FESEM, EDX
and UV–Vis spectroscopy were performed to confirm the synthesis of B2O3
particles and the presence of iron ions in the crystal structure of the
prepared photocatalyst. The novelty of this study was to research the
photocatalytic performance of both B2O3 and Fe-B2O3
photocatalysts.
