Effects of Surfactants on High Regularity of 3D Porous Nickel for Zn2+ Adsorption Application

Abstract EN

Three-dimensional porous nickel (3D-PN) film with large specific surface area (As) and high porosity has been successfully prepared by hydrogen bubble dynamic template (HBDT) method.

This work presents the effects of PEG 10000 and 1,4-butynediol as new additive combination on surface morphology of the PN film.

Meanwhile, the application of 3D-PN in Zn2+ adsorption was preliminarily investigated in the paper.

The surface area is determined as large as 166.7 cm2/mg and the porosity is 0.762 when the concentration of PEG 10000 and 1,4-butynediol was 0.3 g/100 mL and 0.1 g/100 mL, respectively.

The adsorption capacity (Qt and Q (%)) of PN for Zn2+ is observed to be 9.145 mg/g and 0.691 for Zn(NO3)2·6H2O.

The morphology and the microstructure, the product formation, the As the concentration of the metal ions were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), electrochemical impedance spectroscopy (EIS), and atomic absorption spectrometry (AAS), respectively.
