AB - Hemp hurd, which is the major byproduct produced during the extraction of its bast fiber was effectively converted into carbonaceous materials at 400, 500, 700, and 900 °C. The influence of pyrolysis temperature on the physiochemical properties of carbonaceous materials such as elemental composition, ash content, chemical functionality, graphitic content, thermal stability, surface morphology, and particle size, were investigated. The obtained features were then correlated with the electrical conductivity of the produced biocarbon. It was determined that the functional groups present in the biocarbon materials synthesised at lower temperatures (400 and 500 °C) almost disappeared for the biocarbon pyrolyzed at higher temperatures (700 and 900 °C). Raman analysis reveals that the ID/IG ratio of the biocarbon decreases with increased carbonization temperature. This indicates the formation of graphitized carbon clusters at higher temperatures and influences the superior electrical conductivity. In addition, the biocarbon carbonized at 900 °C exhibited the highest thermal stability, carbon content, and graphitic content when compared with their respective low-temperature counterparts. Increasing graphitic nature of the biocarbon materials during the high temperature carbonization along with the decrement of oxygen containing surface functional groups resulted in increased electron transport, which resulted in the biocarbon carbonized at 900 °C having the highest electrical conductivity of 15 S/m.
