The application of nano-nickel oxide

1. Catalyst. As the nano-nickel oxide has a large surface area, in many transition metal oxide oxidation catalyst has good catalytic properties of nickel and nickel oxide nano-composite with other materials, its catalytic effect can be further strengthened. Some rules for the use of a skeleton wrapped in nano-pores of the silica composites of nickel oxide NiO catalytic oxidation of organic amines to achieve better results. Because of this nickel oxide nano-composite material combines the high specific surface area of nanoparticles and the surface of porous silica-rich features, so the catalytic efficiency of the contact area and diffusion have been significantly strengthened. 2. The capacitor electrodes. Cheap metal oxides such as NiO, Titanium dioxide, Co3O4 and MnO2 can replace the precious metal oxides such as RuO2 as a supercapacitor electrode material, the preparation of nickel oxide which is simple, inexpensive, so people pay attention. Preparation of nano-nickel oxide electrode capacitance can often reach 300F / g or so, the number of cycles up to 50O ~ 1000 times. 3. The light absorbing material. As the nano-nickel oxide on the performance of the optical absorption spectra for the selective absorption of such material in optical switching, optical computing, optical signal processing and other areas of its application. Studies with porous anodic aluminum oxide (AAO) template was prepared for the length of 60¼m, diameter of about 200nm of nickel oxide nanotubes, the optical absorption bandwidth than pure bulk nickel oxide crystal is narrower, which shows better selective light absorption characteristics. 4. The gas sensor. As the nano-nickel oxide is a semiconductor material, the use of gas adsorption and conductivity changes can be made to gas resistance. Some people have developed a nano-composite nickel oxide thin films sensors that one of the toxic gas formaldehyde in the indoor monitor. It was also the application of nickel oxide thin films prepared at room temperature under H2 gas sensor can operate. Nano nickel oxide in the optical, electrical, magnetic, catalytic, biological and other fields will be further developed.
