1、catalyst
Nickel Oxide Nanoparticles is a better catalytic oxidation catalyst, Ni2 + has a 3d orbital, has a tendency to multi-electron oxygen adsorbed preferentially on the other reducing gases have the effect of activating and reducing gas O2 plays a catalytic decomposition of organic matter synthesis, conversion processes, such as gasoline hydrocracking, petrochemical processing hydrocarbon conversion, heavy oil hydrogenation process, NiO is a good catalyst. In the catalytic combustion of natural gas, in order to avoid the reaction temperature is too high in the air oxidation of N2 NOx, and unburned CO produced entirely using NiO / CuO-Zr02 composite catalyst to improve its high temperature stability. In the process of the preparation of carbon nanotubes, used in the NiO / Si02 composite catalyst and higher Ni content, high yielding synthesis of carbon nanotubes, the diameter distribution is narrow, and NiO content and shape directly affects the carbon nano Yield and Characters tube. In wastewater treatment, NiO is remove CH4, cyanide, N2, prompting NOx decomposition catalyst. NiO as Photocatalytic Degradation of Acid Red catalyst, in the treatment of organic wastewater, the effect is very significant.
2、glass ceramic additives and colorings
Ceramics by NiO to increase its impact, when added to NiO (O.02 (wt)%), can also improve the electrical properties of materials, such as piezoelectric properties and dielectric properties. Plus NiO in the glass is mainly controlled color glass can absorb ultraviolet in brown coloration stable on transparent glass containing a small amount of NiO. Transparent glass mirrors and decorative glass, are added the right amount of NiO as a coloring agent.
3、Battery Electrode
With the continuous development of communication and information technology, the capacitor has also been an unprecedented development. Because ultracapacitors now has a much higher energy density than electrostatic capacitors and much higher power density than traditional chemical power becomes a hotspot. According to the research showed that ruthenium oxide is the most studied, the best performance of an electrochemical capacitor electrode material, but because it’s very expensive hindered its large-scale application. Activated carbon resistance and larger features make it sights on transition metal oxides. The transition metal oxide because of its own quasi-capacitance phenomenon as an electrode material for supercapacitors. Currently, the use of Ni, Mn, Co and other oxides of resistance is small, inexpensive, and is larger than the capacity and other characteristics, battery electrode materials made of concern. Molten carbonate fuel cell using NiO as the cathode, with gas or natural gas as fuel, is a power generation efficiency than conventional thermal power of clean energy. And nano-NiO battery Compared with ordinary NiO battery has obvious advantages discharge, the discharge capacity significantly increased, electrochemical performance is improved.
4、Sensor
NiO is more and more attention in recent years, gas sensor material. At present, made into nano NiO formaldehyde sensor, CO sensor, H2 sensors used in actual production.
