Facile synthesis of hexagonal Ni0.85Se nanosheet and its application as adsorbent and catalyst to dyes

The Ni0.85Se nanosheets were prepared by a facile hydrothermal method. By using NaBH4 as assistant, the Ni0.85Se nanosheets showed excellent adsorption to MB and high catalytic activity to the hydrogenation of PNP. The Ni0.85Se nanosheets were successfully used to treat both MB and PNP synchronously.
