Aims: To synthesize Nano sized ZnO/MnO2/Gd2O3 ternary heterostructures for enhanced photocatalysis.

Background: The color dyeing process involves mixing of dyes in water or any other organic solvents and the cloths are dipped and retained in the color bath till the cloths get properly dyed. Later the color bath is disposed off as effluents in open streams and drainages. This has resulted in a major water pollution problem in the areas surrounding the dyeing units.

Objective: To use perised curd as a fuel for the synthesis To utilize freely available sunlight To degrade the color effluent effectively.

Method: Combustion method is applied to prepare nanomaterials.

Result: Prepared ternary heterostructures of ZnO/MnO2/Gd2O3 are effective under visible light More than 90% of the dye has been degraded.

Conclusion: Perished curd is used to produce ZnO-MnO2-Gd2O3 nanostructures.

● Solvent-free synthesis of ZnO-MnO2-Gd2O3 nanostructures.

● Very stable ZnO-MnO2-Gd2O3 heterostructures are produced by this method.

● Synthesised ZnO-MnO2-Gd2O3 heterostructures show better photocatalytic properties.

Other: This procedure can be scaled up for industrail operation.
