A New Method to Characterize the Porous Carbon Materials

Compared with the traditional materials, carbon materials exhibit excellent physical, electrical, mechanical and chemical properties. Porous carbon is one of the structured carbon materials, with controlled large surface area, high surface activity, low density, superior chemicals, corrosion resistance and uniform pore features on micrometer and nanometer scales. It is explored as advanced material in lithium-ion batteries, Super capacitor, fuel cell, energy storage and conversion devices, and adsorption materials, because of its excellent property. The characterization methods were the traditional instruments, such as transmission electron microscopy, scanning electron microscopy, Raman spectrum, X-ray diffraction, X-ray photoelectron spectroscopy and infrared spectroscopy. This article demonstrated new method to character the porous carbon with coherent anti-stokes Raman microscopy.
