摘要：

In this review, current progress in the area of photocatalysis using energy efficient Light Emitting Diodes (LEDs) as an irradiation source is discussed. LEDs are small in size, robust, do not contain mercury, have a longer life span than conventional light sources, and can operate on a direct current. These properties of LEDs offer a new alternative to traditional ultraviolet sources and open new possibilities for photocatalytic degradation with reduced power consumption, along with greater freedom in the design of various types of photocatalytic reactors. The present review mainly focuses on the photocatalytic degradation of organic compounds and dyes as well as the sterilization of microrganisms which are present in water and air, using irradiation by various types of LEDs, photocatalytic reactors, and catalysts. In addition, future prospects and challenges for the application of LEDs for to photocatalytic environmental pollutant degradation have been highlighted.
