Rice husk and rice husk ash reutilization into nanoporous materials for adsorptive biomedical applications: A review

  • Wee-Keat Cheah , Chee-Heong Ooi and Fei-Yee Yeoh
From the journal Open Material Sciences


The continuous generation of rice husk biomass makes this waste biomass a consistent and renewable resource for carbon zero power generation. Biochar from the power generation industry could be further utilized and converted into activated carbon through a simple activation process, foregoing the conventional carbonization process. Complete combustion of rice husk into rice husk ash could be subsequently processed into sodium silicate with little difficultly since more than 90%of the rice husk ash constituent is silica. Sodium silicate is used mainly as a precursor for both the synthesis of mesoporous silica and zeolite. This paper reviews on the various nanoporous adsorbents derived from a single rice husk biomass.
