From the 125 ~ 250 °C C degrees, within the context of temperature increase heat-treatment with compound particles, the CD-degradable reaction rates increase after first-come-first-served basis is constant temperature heat-treatment, when reduced to 150 from the compound particles °C the light-catal

In from 125℃~250℃ the scope, along with the heat treatment temperature increase, after the compound particle light degradation reaction speed constant increases first reduces, when heat treatment temperature for 150℃ obtains compound particle photochemical catalysis activeness is highest.

In the range from 125 ¡æ ~250 ¡æ, as the heat increases, photodegradation reaction rate constants of composite particles first increase and then decrease, when heat treatment temperature of 150 ° c, the resulting composite particles of high photocatalytic activity.
