"Sustainable synthesis of silicon nitride nanowires using waste"
Waste carbon fibre reinforced polymer (CFRP) is challenging to recycle due to its complex composition (i.e fibre, matrix, and filler materials) and is therefore mostly sent to landfill. A novel approach is reported to synthesise silicon nitride (Si3N4) nanowires using CFRP waste as a reducing agent to step forward in sustainability by closing the recycling loop. A vapor-solid mechanism has been proposed to describe the use of waste CFRP as a source of carbon and reducing gas and silica as a source of silicon to synthesise Si3N4 nanowires under nitrogen atmosphere at 1450 °C.
