Photodegradation of Toxic Dyes by using Spinel Nano-Composite: A Short Review
Abstract
Water pollution is now a growing issue due to rapid growth in industrialisation which makes difficult to find a balance between the growing population and the availability of clean water. Various types of semiconductors have been discussed by previous researcher but they have some drawbacks which makes metal oxide of spinal structure an emerged photocatalyst due their smaller band gap. In this paper we have discussed various spinal composite ,their various methods of preparation and their photo degradation efficiency on different dyes. Mixed transition metal oxides' photocatalytic action can be attributed to their spinel structure, tiny particle size, and vast surface area. Different spinel composite like FeCo2O4,MnCo2O4,ZnCo2O4 showed enhanced photocatalytic efficiency of 89.02%,74.83% and 77.5% against MB at about 110 min where as g-C3N4 and NiFe2O4 gave 90% and 98% at 225 min.
