First, zinc acetate dihydrate solution is prepared by dissolving 2.195 g of zinc acetate dihydrate in 100 ml distilled water/ethanol, and stirred in ambient atmosphere conditions. Then potassium hydroxide (1.122 g dissolved in 10 ml distilled water) is added to the just prepared solution dropwise under continuous stirring. After a few minutes, a milky white solution is obtained. This prepared mixture is further heated for 3 h at 80–90°C without stirring. The resulting suspension is centrifuged to retrieve the product, and the mixture is washed with distilled water in an ultrasonic bathwater and then the powder is dried at 70°C overnight [43].

In a typical synthesis, zinc acetate (Zn(CH₃CO₂)₂·2H₂O.) of 5.0 × 10−3 M and polyvinylpyrrolidone ((C6H9NO)n) of 0.12 g had dissolved well in a round bottom flask (100 ml volume size) of containing ethanol (90 V/V) of 30 ml. The homogeneous mixture was heated to 95°C under vigorous stirring in a reflux setuptill the transparent-solution turn into milky-white. The pot was cooled down to room temperature after 3 h reaction. For Au deposition, chloroauric acid of 0.02 mM was mixed well in the white solution. Again, the reaction mixture was heated and maintained at 75°C for 2 h under stirring. The collected purple colored Au/ZnO nanocomposites were cleaned with ethanol and acetone for some times and dried.
