Synthesis, characterization, and photocatalytic activities of Eu3+-doped BiVO4 catalysts
View through CrossRef
An improved sol-gel technique was utilized to synthesize the Eu3+-doped bismuth
vanadate (BiVO4) photocatalysts, resulting in enhanced photocatalytic activity. The
photocatalytic properties and structural composition of the catalyst were rigorously
examined by XRD, SEM, EDS, XPS, and DRS. The XRD analysis confirmed the
successful incorporation of Eu3+ into the host lattice of BiVO4. The photocatalytic
measurements demonstrated that Eu3+ doping significantly enhanced the photocatalytic
efficiency of the BiVO4, with the 7% Eu3+-doped BiVO4 sample exhibiting the highest
photocatalytic activity. The boosting of photocatalytic efficiency can be caused by the
additional oxygen vacancies, narrower band gap, and decreased rate of photoexcited
electron-hole pair recombination caused by Eu3+ doping.
