Due to bad consequences and harmful effect of dye contaminated waste water for living being and owing of complex structures and high thermal and photostability of synthetic dyes, several methods were implemented to utilize maximum visible light. One of the effective approaches is coupling of semiconductors to create a heterojunction for interfacial charge transfer. In this ramification, we utilize graphene oxide-(GO)-based metal semiconductor nanocomposites. Anion controlled sulfidation for the decoration of graphene oxide with iron cobalt sulphide was achieved in a simple hydrothermal reaction. Without any templates or back bone architecture, in an easy and economical way we can tune the morphology, surface area and band gap via anion exchange using different precursor that influence its dark catalytic activity for the removal of organic dyes (rhodamine B, methylene blue, methyl orange and their mixture). The synthesized catalyst was very much active and reusable that gave quantitative removal efficiency. |
