Effects of a buffer on the structure and catalytic activity of Pd nanostructures obtained from biomineralization were evaluated. Significant structural differences attributed to the buffer were observed. In addition, the Pd nanostructures prepared in buffered solutions had enhanced catalytic activity in the reduction of aminonitrophenol isomers. Our findings emphasize that the buffer selection is critical for biomineralization. Moreover, these findings indicate that the buffer can be possibly used to control the structure and activity of Pd nanomaterials, which is a very simple and cost-effective way compared with other methods.
