Abstract: The effect of different pH value on the morphology of palladium particles was investigated by using Ginkgo biloba extract as reducing agent.Firstly,the prepared palladium simple particles were characterized by X-ray diffraction and transmission electron microscopy.Secondly,the morphology of particles was investigated by scanning electron microscopy.The results showed that the pH value of the reaction solution can control the size and morphology of particles.The results showed that the size and morphology can be controlled by changing the pH of the reaction solution.The formed palladium particles had spherical,linear,triangular and other regular geometric shapes.When the pH was acidic,it was advantageous to prepare linear particles.When the pH was alkaline,it was advantageous to prepare spherical particles.When the pH was neutral,it was advantageous to prepare regular shape and smaller size palladium particles.
