Nickel Hydroxide Nanopowder Water Dispersion ( Ni(OH)2, 20wt%, 15-20nm)

Nickel Hydroxide Nanopowder Water Dispersion (Ni(OH)₂, 20 wt%, 15-20 nm) is a water-based dispersion that contains Nickel Hydroxide (Ni(OH)₂) nanoparticles. Here are the key details and properties of this material:

1. Composition and Properties:

• Material: The dispersion contains Nickel Hydroxide (Ni(OH)₂) nanoparticles, which are a common inorganic compound of nickel. Nickel Hydroxide is widely used in energy storage (e.g., in batteries) and catalysis due to its high electrochemical activity.
• Purity: The product contains 20 wt% Nickel Hydroxide nanoparticles, ensuring that there is a suitable concentration of the material for use in various applications.
• Particle Size: The nanoparticles are sized between 15-20 nm, which is small enough to increase the surface area and reactivity compared to bulk material, making them ideal for applications in catalysis, energy storage, and sensor technologies.
• Dispersion: This material is in a water-based dispersion, meaning that the nanoparticles are suspended in water, which makes them easier to handle and apply in many industrial and laboratory processes.

2. Key Features:

• Water-Based: Being water-based, this dispersion is environmentally friendly and safer to handle compared to solvent-based dispersions. It is less toxic, easier to work with, and less likely to cause environmental harm.
• High Surface Area: With a 15-20 nm particle size, the Nickel Hydroxide nanoparticles have a large surface area relative to their volume. This feature is important for applications requiring high reactivity, such as in electrochemical reactions and catalysis.
• Moderate Concentration: The 20 wt% concentration provides a balanced amount of Nickel Hydroxide for many applications where a moderate level of material is required, such as in battery electrodes or catalytic processes.

3. Applications:

• Energy Storage: Nickel Hydroxide is a key material in the production of Nickel-Metal Hydride (NiMH) batteries, where it is used as the positive electrode material. The dispersion can be used in battery manufacturing to form electrode materials with improved electrochemical properties.
• Catalysis: Ni(OH)₂ is used as a catalyst or a catalyst precursor in various chemical reactions, including hydrogenation, dehydrogenation, and oxygen evolution reactions. The nanoparticle size enhances its catalytic efficiency by increasing the active surface area.
• Electronics and Conductive Films: Nickel Hydroxide nanoparticles can be used in electronics for creating conductive films or coatings. The water-based dispersion allows easy application of these films for electronic components.
• Sensors: Nickel-based materials like Ni(OH)₂ are used in sensor technologies, particularly in sensors for detecting gases or other chemical compounds. The high surface area of the nanopowder makes it suitable for sensitive detection of various gases, such as CO or NO₂.
• Electrochemical Supercapacitors: Nickel Hydroxide is also employed in supercapacitors for energy storage applications, as it provides excellent capacitive behavior when used in electrode materials.
• Water Treatment: Nickel Hydroxide has potential applications in water purification and wastewater treatment, where it is used to adsorb heavy metals or neutralize acids in industrial processes.

4. Advantages:

• High Surface Area: The 15-20 nm particle size results in a large surface area, which enhances the electrochemical activity, catalytic properties, and reactivity of the material.
• Water-Based: The water-based dispersion is easier and safer to handle compared to organic solvent-based dispersions, making it more environmentally friendly and user-friendly.
• Versatility: Nickel Hydroxide nanoparticles are versatile and can be used in various energy storage devices, catalytic applications, electronic coatings, and sensor technologies.

5. Handling and Storage:

• Storage: Store the dispersion in a cool, dry place, away from direct sunlight and heat. Ensure that the container is tightly sealed to prevent evaporation of the water and maintain the stability of the dispersion.
• Handling: Wear appropriate personal protective equipment (PPE), such as gloves, goggles, and lab coats, when handling the dispersion to avoid direct contact with nanoparticles.
• Safety: While Nickel Hydroxide is generally safe for industrial applications, precautions should still be taken to avoid inhalation or skin contact with the nanoparticles. Proper ventilation is recommended when handling the material.

6. Potential Limitations:

• Limited Reactivity at Larger Sizes: Although 15-20 nm particles provide a large surface area, Nickel Hydroxide nanoparticles may not be as reactive as smaller-sized particles in some highly sensitive catalytic reactions.
• Stability: The nanoparticles may aggregate or settle in the dispersion over time, requiring stirring or agitation before use to maintain uniformity.
