Practical application of nano nickel oxide

1. Nano nickel oxide used in catalyst:

Nano-nio (VK-N10,VK-N30,VK-N150, wan King supply) is a good catalytic oxidation catalyst, Ni2+ has a 3D orbital, has the preferred adsorption tendency of multi-electron oxygen, also has the activation effect on other reducing gases, and the O2 of reducing gases play a catalytic role, in the decomposition synthesis of organic matter, transformation process, Such as gasoline hydrogenation cracking, is the petrochemical process of hydrocarbon conversion, heavy oil hydrogenation process, nano NiO is a good catalyst. In the catalytic combustion of natural gas, the NiO/CuO — Zr02 composite catalyst is used to improve its high temperature stability in order to avoid the oxidation of N2 in the air to NOx at high reaction temperature and the generation of unburned CO. In the process of preparing carbon nanotubes, NiO/Si02 composite catalyst is used. When the content of Ni is high, the yield of synthesized carbon nanotubes is high and the diameter distribution is narrow. The content and shape of NiO directly affect the yield and properties of carbon nanotubes. In wastewater treatment, NiO is a catalyst to remove CH4, cyanide, N2, and promote NOx decomposition. As a photocatalytic catalyst for acid red degradation, nanometer NiO has a remarkable effect in the treatment of organic dye wastewater.

2. Nano nickel oxide for ceramic additives and glass dyes:

Ceramic products with nano-NiO (VK-N10,VK-N30,VK-N150, million view supply) to improve the impact force, when NiO(O. 02(wt) %), can also improve the material’s various electrical properties, such as piezoelectric properties and dielectric properties. The addition of nanometer NiO in glass is mainly to control the color of the glass. A small amount of NiO is contained in the stable brown transparent glass which can absorb ultraviolet light. A proper amount of nano-NiO was added as colorant in both transparent glass and decorative glass.

3. Nano nickel oxide applied to sensors (VK-N10,VK-N30,VK-N150, million View supply) :

NiO is a gas sensor material which has been paid more and more attention in recent years. At present, formaldehyde sensors, CO sensors and H2 sensors made of nano NiO have been used in practical production.

4. Nano nickel oxide for battery motor materials:

Ordinary nickel oxide battery discharge 30 minutes, the terminal voltage is close to exhaustion, and nano nickel oxide (VK-N10,VK-N30,VK-N150, ten thousand king supply) battery to 90 minutes after the failure, showing good discharge performance. The reason for this is that these nanoparticles and conductive materials are distributed in the gap between the active material in the positive electrode, which facilitates the transfer of both electron charge and ionic charge. And the small size effect increases the voidage of the active substance and the surface area of the reaction. Ordinary nickel oxide battery at the beginning of the performance of a large current charging, and nano nickel oxide battery is shown as a small current charging, 60min after the current tends to be equal, showing good charging performance. So nano – nickel oxide battery has excellent application prospect. Studies have shown that granular nickel oxide has better electrochemical performance and higher specific capacitance than needle nickel oxide.

(1) Application of new photoelectric chemical Solar Cells (DSSC) :

In order to improve the efficiency and stability of DSSC, HeJia~ UN et al. (VK-N10,VK-N30,VK-N150, supplied by MSCR), NiO was used as a cathode in DSSC for the first time considering its advantages of stability and wide gap as a P-type semiconductor.

(2). Application in electrochemical capacitors (VK-N10,VK-N30,VK-N150, 10000 king Supply) :

Although the transition metal oxides RuO and IrO have large specific capacity as electrode materials, their commercialization is limited due to high cost. The sea urchin-like nanometer NiO electrode materials made by LiuXianming et al have typical capacitance properties. The constant current charge-discharge experiments have proved that the specific capacity of the electrode materials can reach 290F/g, and it still has 217F/g after 500 cycles. WangYonggang etc.. The capacitance of ordered hollow structure nano-NiO synthesized by using SBA – 15 template can reach 120F/g. There is also a composite material made of batteries such as lithium nickel cobalt oxide (LINIXC01.X02) battery, it combines the advantages of LiNi02 and LiC002, has high voltage, discharge voltage stable, large capacitance, low temperature performance, no pollution and long working life and other advantages.
