Abstract

The need for sustainable development of our technologies has put focus on nanostructured carbons prepared from low-cost, abundant and sustainable resources like vegetable biomass and agricultural by-products and wastes. Bio-carbons are being heralded as a solution to many agricultural and environmental issues, but there is still a need for the use of these materials in higher aggregate value applications, such as energy storage and harvesting devices, as well as light-weight composites. For these applications, the physico-chemical properties of the bio-carbons need to be tuned and assessed, so that the desired performances are achieved. Bulk and surface chemistry, electrical and thermal conductivity, particle size and aspect ratio, porosity, and surface area, among other properties, have critical influence on the performance of bio-carbons in energy and engineering materials.
