报告内容简介：With the increase of the population and affluence over the past decades, the amount of solid wastes generated by the industry, agriculture and householders each year keeps rising in the world. Rice husk is one of the important agricultural waste containing organic mass and bio-silica. Value-added conversion of rice husk to silicon carbide (SiC)-based materials satisfies the demand of the reutilization of the solid wastes and also promises a closed loop of carbon cycle. SiC materials with different morphologies including microscale and nanoscale particles, nanoscale whiskers and nanowires can be prepared by high temperature carbothermal reaction from rice husk with or without metal catalysts under inert gas atmosphere. SiC-based composites including SiC nanowires/C, Al/SiC, SiC/Si3N4and SiC/Al2O3can be obtained using rice husk as the main source materials. SiC-based materials exhibit great application potential in the fields of absorbents, optical devices, mechanical products, photocatalysts, semiconductors and Li ions batteries.
