Construction of amorphous In2S3 decorated Ta2O5-x mesocrystals for enhanced photocatalytic tetracycline degradation
Fabrication of tantalum-based composite photocatalysts with high-performance for dealing with organic pollutants remains valuable and highly urgent nowadays. In this work, amorphous In 2 S 3 decorated Ta 2 O 5-x mesocrystals were fabricated for tetracycline degradation under visible-light irradiation. The introduction of amorphous In 2 S 3 highly improved the visible-light absorption and charge separation, and the prepared In 2 S 3 /Ta 2 O 5-x mesocrystals showed highly enhanced photocatalytic performance towards tetracycline degradation, and the corresponding rate constant was approximately 0.00658 min −1 , which was 5.58 times that of In 2 S 3 and 3.64 times that of Ta 2 O 5-x mesocrystals. The enhanced visible-light photocatalytic performance for the In 2 S 3 /Ta 2 O 5-x mesocrystals was mainly attributed to the fabrication of strongly combined interface between In 2 S 3 and Ta 2 O 5-x mesocrystals.
