Herein, we report an environmentally benign method for the preparation of Pt, Au and Pd NPs in water. Water insoluble alkali lignin (AL) and hemicellulose was used soly as the reducing and protecting agents. Both of the AL and hemicellulose show excellent reduce ability in the metal precursor reduce process. The solid AL could support the obtained metal NPs. The metal particles reduced by hemicellulose are aggregated and the extent of aggregation increased along with the time.
