High-purity nano nickel oxide

Product Features

High-purity nano nickel oxide is prepared by plasma vapor phase combustion method, featuring high purity, small particle size, uniform distribution, large specific surface area, clean surface, no residual impurities, and low bulk density. It is easy to disperse, overcoming the drawbacks of hard agglomeration, poor dispersibility, and low purity commonly found in wet chemical methods. As a functional material, nano nickel oxide is widely used in industries as a catalyst, semiconductor material (varistor, thermistor), magnetic material, and raw material for glass and ceramic coloring agents.

Product Parameters

Product Applications

1. Nano nickel oxide in catalysts: Nano NiO is an excellent oxidation catalyst. Ni²⁺, with its 3d orbitals, tends to preferentially adsorb multi-electron oxygen and activates other reducing gases, catalyzing the reaction with O₂. It is widely used in the decomposition, synthesis, and transformation of organic compounds, such as gasoline hydrocracking, hydrocarbon conversion in petrochemical processing, and heavy oil hydrogenation. Nano NiO also serves as an effective photocatalyst for degrading acid red dyes in organic wastewater treatment.

2. Nano nickel oxide in ceramic additives and glass coloring agents: In ceramic products, nano NiO enhances impact resistance. Adding 0.02 wt% NiO improves electrical properties such as piezoelectric and dielectric performance. In glass, nano NiO is used to control color, particularly in stable brown transparent glass that absorbs ultraviolet light. It is also added as a coloring agent in transparent glass mirrors and decorative glass.

3. Nano nickel oxide in battery materials: With the continuous development of communication and information technology, capacitors have become a research hotspot due to their higher energy density compared to electrostatic capacitors and higher power density compared to traditional chemical power sources. Although ruthenium oxide is a well-studied and high-performance electrochemical capacitor material, its high cost limits large-scale application. Transition metal oxides, such as NiO, MnO, and CoO, are gaining attention for their low internal resistance, affordability, and high specific capacity. In molten carbonate fuel cells, NiO is used as a cathode with coal or natural gas as fuel, offering higher power generation efficiency than traditional thermal power. Nano NiO batteries exhibit significant discharge advantages, increased discharge capacity, and improved electrochemical performance compared to conventional NiO batteries.

4. Nano nickel oxide in sensors: NiO has gained increasing attention as a gas sensor material in recent years. Nano NiO-based sensors for formaldehyde, CO, and H₂ are already used in practical applications.

Product Characterization

Packaging and Storage

This product is packaged in inert gas-filled plastic bags and should be stored sealed in a dry, cool environment. It should not be exposed to air to prevent moisture-induced oxidation and agglomeration, which may affect dispersion performance and efficacy. Packaging quantities can be customized according to customer requirements, including sub-packaging.
