Аннотация: Nanoporous silicon carbide with a specific surface area of up to 186.45 m2 g−1 has been efficiently synthesized from waste rice husk using a magnesiothermic reduction at 950 °C as a key step. Throughout the entire process, the recovery rates of silicon, potassium and phosphorus from rice husk can reach 88.46, 91.5 and 65.5%, respectively. Turning rice husk waste into a real treasure, this promising method for producing porous SiC protects the environment and brings economic benefits.

Ключевые слова: rice husk, nanoporous silicon carbide, high purity, magnesiothermic reduction, naturally porous structure, phosphorus–potassium compound fertilizer.
