Abstract

The two-layer member of Aurivillius compound ABi2Ta2O9 (A= Ca, Sr, Ba) has been reported can be applied as photocatalyst material. In this research, the compound ABi2Ta2O9 (A= Ca, Sr, Ba) was synthesized using the molten salt method and measured photocatalytic act ivity to degrade methylene blue. Difractogram samples showed that the compound ABi2Ta2O9 (A= Ca, Sr, Ba) was successfully obtained but st ill found impurit ies on the samples. Micrograph samples showed that the particle morphology of ABi2Ta2O9 (A= Ca, Sr, Ba) was plate-like and found agglomerat ion in all part icles. The calculat ion using the Kubelka-Munk equat ion exhibited that CaBi2Ta2O9, SrBi2Ta2O9, BaBi2Ta2O9 sequent ially have bandgap energy of 3.51, 3.21, and 2.44 eV. The degradat ion test results of methylene blue solut ion show that CaBi2Ta2O9, SrBi2Ta2O9, and BaBi2Ta2O9 materials can degrade sequent ially by 14.44, 24.23, and 15.99 % for 80 minutes
