Facile synthesis of zinc aluminate nanostructures through an epoxide driven sol–gel route

ZnAl2O4 nanostructures have been synthesized following a facile epoxide addition, sol–gel route. Upon gelation, these highly amorphous materials can be annealed at 600 °C to yield purely crystalline ZnAl2O4 nanostructures. This method allows for control of desired physical properties such as high surface area, high porosity and small crystallite size.

► We use the epoxide addition sol-gel method to prepare zinc aluminate nanocrystals.
► Increasing annealing temperature to 600 °C results in crystalline zinc aluminate.
► The epoxide addition method allows for control over morphology and particle size.
► A useful catalyst can be prepared cost efficiently through this method.
