Effect of the carbonization temperature of plant biomass on the structure, surface condition and electrical conductive properties of carbon nanoporous material

Abstract

In this work, we have obtained a nanoporous carbon material (CM) from walnut shells using the method of thermal carbonization. Moreover, the in uence of the carbonization temperature of the raw material on the electrical conductivity of the CM obtained by Raman, infrared (IR), and impedance spectroscopy has been investigated. Consequently, to analyze the evolution of the electrical conductivity of the material with an increase in the carbonization temperature, the theory of percolation has been applied.
