Product Information: Three-dimensional porous nickel/nitrogen-doped tri-cobalt tetroxide composite film

Product color: black
Physical scale: no more than 2cm*2cm
Macropore diameter: The characteristic macropore diameter is 5-20 microns, and the internal channels are three-dimensionally connected.
Film thickness: about 30-90 microns
Load capacity: 2-5 mg cm^-2
Thickness and diameter of nitrogen-doped cobalt tetroxide nanosheets: thickness 5-15 nm, diameter 100-300 nm
Base information: Nickel sheet base thickness 0.1-0.3 mm
Note: The stem of the nickel film is composed of micro/nano nickel particles (500 nm-1μm), and there are a lot of voids between the particles. Three-dimensional porous nickel has a porosity of 99% and a relative specific surface area 5-10 times that of ordinary commercial nickel foam. Good conductivity and high electrochemical activity. The material is relatively fragile, the transportation needs to be transported gently, and manual transportation is the best. Cobalt tetroxide nanosheets are supported on porous nickel to form a composite film.
Application fields: electrochemical energy storage (lithium battery, sodium battery, potassium battery, zinc battery, zinc battery, lithium battery, water battery, lithium-sulfur battery, metal battery, etc.), electrocatalysis (hydrogen evolution, chlorine evolution, oxygen evolution, oxygen reduction , Nitrogen reduction, carbon dioxide reduction, etc.), supercapacitors, electroanalytical chemical carriers, electrochemical sensing (ethanol and glucose concentration detection, methanol detection, etc.), formaldehyde decomposition catalysis, flexible electrodes and flexible electrons, metal ion separation filtration, photocatalysis Decomposition degradation, environmental degradation degradation VOC, heavy metal ion adsorption, hydrodynamic testing, etc.
Harmful: harmless and non-toxic, but inedible
Product packaging: 2 pieces/pack
