Abstract

The invention discloses a nickel-tin alloy-based nanosphere structure composite material and a preparation method thereof. The nickel-tin alloy-based nanosphere structure composite material is of a nanosphere structure composed of a partially-graphene carbon matrix and nickel-tin alloy-based nanoparticles embedded in the carbon matrix. The preparation method comprises the following steps: preparing a nickel-tin binary glycerate nanosphere material, and carrying out one-step heat treatment by taking the nickel-tin binary glycerate nanosphere material as a precursor to prepare the nickel-tin alloy-based nanosphere structure composite material. The method disclosed by the invention is novel in thought, simple and convenient to operate, short in synthesis period and low in cost, and the nickel-tin alloy-based nanosphere structure composite material prepared by the method disclosed by the invention has great application potential in the energy storage fields of lithium batteries, sodium batteries and the like.

Description

technical field [0001] The invention belongs to the field of inorganic nanocomposite materials, in particular to a nickel-tin alloy-based nanosphere structure composite material and a preparation method thereof. Background technique [0002] Organic-inorganic coordination complex (Organic-inorganic coordination complex) is a kind of crystalline porous material with network structure formed by the interconnection of inorganic metal centers (metal ions or metal clusters) and bridging organic substances through coordination. . Due to their porous, large specific surface area, rich and diverse structures, and multimetallic sites, these materials have been widely used in many fields, such as catalysis, sensors, optics, molecular magnets, and anticancer drugs. Although metal coordination hybrids have been extensively studied in energy-related fields and applications, there are few reports on their use as templates / precursors for energy conversion and energy storage devices.
