In view of the current study's demonstration of the synthesis of clay-doped ZnO composites,we present a low-cost method for producing clay-metal oxide(clay/ZnO).Utilizing the solution combustion technique,a composite of clay/ZnO was produced utilizing citric acid as both a fuel and a complexing agent.The hexagonal unit cell structure of the created clay/ZnO may be seen using XRD patterns.The ZnO-infused clay was visible in FE-SEM micrographs as homogenous,sphere-shaped ZnO.The possible involvement of clay/ZnO photocatalytic activity in the UV-induced photodegradation of malachite green dye was investigated.The 90％degradation rate shows the composite's outstanding photocatalytic degradation capacity.The resulting substance was electrochemically analyzed using a constructed electrode in 0.1 M KOH electrolyte.It increased its sensor capabilities,which now include chemical and biomolecule sensors,and it excelled in cyclic voltammetry-based redox potential studies.To efficiently evaluate chemically synthesized NPs for electrochemical,sensing,and photocatalytic applications,this study intends to create a solution combustion procedure for the synthesis of clay/ZnO nanocomposite using urea as fuel.
