摘要：

Synthesis of silicon carbide agricultural waste-derived activated carbon composite nanomaterials is demonstrated at heating rates of 25-100 degrees C up to 1600 degrees C in vacuum. The synthesis technique utilizes a novel free-pressureless spark plasma sintering (FPSPS) process. Improved macroscopic structural integrity is achieved through the development of SiC nanowire networks and preliminary specific surface area values of 69 m(2) g(-1) are measured, exhibiting potential application in catalyst support and adsorption applications. The advantages and potential of FPSPS processing for this material system are discussed. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
