| Summary: | Scientists evaluated the influence of ultrasound on the photodegradation of salicylic acid on four different commercially available formulations of titania powder. Techniques used to isolate the system characterized by the highest enhancement performance are described. Utilization of ultrasound methods during the course of photocatalysis strongly impacted the rate and efficiency of salicylic acid destruction as compared to tests investigating the destruction potential of ultraviolet light photocatalysis acting alone. Several potential reasons for observed increases in activity under ultrasonication are discussed, including aggregate breakage and photocatalytic utilization of species generated by the ultrasound. Synergistic effects observed for catalysts with small particle sizes are examined. |
