The study investigated the impact of synthesis conditions on the characteristics of hybridized ZnO nanocomposites and the photodegradation kinetics of Triclopyr using hydrothermally synthesized ZnO/CuO materials. It was found that synthesis conditions greatly influence the morphology, particle size, and crystal growth of nanomaterials.
In the current study, we have explored the consequences of synthesis conditions on optical, morphological, and photoluminescence characteristics of hybridized ZnO nanocomposites. The photodegradation kinetics of Triclopyr, a pesticide, using hydrothermally synthesized ZnO/CuO materials at various synthesis conditions were also studied. The prepared samples were characterized by various techniques such as UV-vis spectrophotometer, field emission scanning electron microscopy (FESEM), elemental dispersive X-ray analysis, and photoluminescence spectrometer. From FESEM images, it was revealed that the synthesis conditions greatly influence the morphology of nanomaterials, particle size, nucleation, and crystal growth. To evaluate the percentage composition of elements present in synthesized materials, elemental analysis with mapping was performed. The band gap values were calculated using Kubelka Munk's plot. The band gap values decrease on CuO incorporation and lie near infrared region. Effect of scavengers and pH on degradation kinetics were also explored. The complete mineralization of Triclopyr was achieved in 100 min. The synthesized materials are found energy efficient and helpful in environmental purification.
