Application of luminescence for estimating the efficiency of photocatalysts

Capabilities of new approaches in luminescence applications for estimating the quality of photocatalysts have been studied. Since photoluminescent processes are chain ones and initiated by free radicals, luminol and other indicators can be used to determine the efficiency of photocatalysts: the high...

Description
Summary:Capabilities of new approaches in luminescence applications for estimating the quality of photocatalysts have been studied. Since photoluminescent processes are chain ones and initiated by free radicals, luminol and other indicators can be used to determine the efficiency of photocatalysts: the higher is the intensity of luminescent glow, the more is the number of free radicals in the system and the higher is the efficiency of photocatalyst. In some cases, by using special techniques it is possible to study the accumulation of superoxide radicals, hydroxyl radicals, and hydrogen peroxide in the system.
