Pt-TiO2 composite electrode ultrasonic Photocatalytic Properties of Organic Compounds
Abstract
Acousto-optic catalytic reaction is photocatalytic traditional applications in wastewater treatment developed.Pt contains the TiO2 nanotube at a fixed carrier,the active substance is not easy to fall off,to a certain extent can be reused.At the same time,ultrasound can also degrade organic pollutants.This study used the first anodic oxidation of titanium at the surface of TiO2 nanotube arrays obtained through ultrasound-assisted Preparation of Pt-TiO2 nanotube arrays.Secondly,the use of Pt-TiO2 nano-array composite photocatalytic degradation,ultrasonic degradation,ultrasonic and photocatalytic degradation of organic compounds (methylene blue).Comparison of photocatalytic degradation,ultrasonic degradation and ultrasonic properties of photocatalytic degradation of organic matter and ultrasonic frequencies,power,time Sonophotocatalytic containing Pt time to Pt-TiO2 nanotube array degradation process of organic pollutants.Come to the conclusion:the introduction of ultrasound to enhance the advancement of the Pt-TiO2 nano-array composite photocatalytic degradation of organic matter degradation rate; degradation rate is affected by reaction time,ultrasonic power,frequency; increase in the time set Pt can enhance the degradation of organic matter rate.
Key words:photocatalysis,ultrasound,titanium dioxide,platinum,degradation of methylene blue
