Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The present invention proposes a simple method for preparing vertically arranged bimetallic hydrotalcite nanosheets in large quantities, using three-dimensional graphene foam, porous carbon foam, or porous metal foam as a conductive matrix, and changing the metal salt precursor and its concentration. Crystallization of bimetallic hydrotalcites by hydrothermal reaction at different temperatures.

[0021] The specific preparation operation steps take the preparation of iron-nickel hydrotalcite nanosheets as an example:

[0022] (1) nickel nitrate, ferric nitrate, urea are dissolved in appropriate amount of water, and it is transferred in the hydrothermal reaction kettle;

[0023] (2) Immerse the conductive substrate (three-dimensional graphene foam, porous carbon foam, or porous metal foam) in the reaction solution of the hydrot...

Abstract

The invention relates to a preparation method for a vertically arrayed bimetallic hydrotalcite nanosheet. The preparation method uses three-dimensional graphene foam, porous carbon foam or porous metal foam as a conductive matrix and carries out crystallization on bimetallic hydrotalcite via a hydrothermal reaction at different temperatures by changing the concentration of a metal salt precursor. The preparation method is simple in process, easy to realize batch production and good in applicability and can prepare vertically arrayed bimetallic hydrotalcite nanosheets having different reaction activity and based on any metal as needed.

Description

technical field [0001] The invention relates to a preparation method of hydrotalcite nanosheets, in particular to a preparation method of vertically arranged bimetallic hydrotalcite nanosheets, belonging to the technical field of nanomaterials. Background technique [0002] The structure of hydrotalcite is derived from pyroaurite- structure. [0003] pyroaurite- The structure is a three octahedral brucite layer with six oxygen atoms as the hydroxide coordination centered on the cation. In the hydrotalcite structure, certain divalent metal ions are replaced by isostructural trivalent metal ions, resulting in a net positively charged metal hydroxide layer. Metal hydroxide layers are stacked on top of each other, with interlayers consisting of water molecules and charge-compensating anions. As anion exchangers, adsorbents, and catalysts, hydrotalcite has many applications in chemical, energy, and environmental fields. [0004] At present, the synthesis of hydrotalcite ha...
