Abstract

The main research efforts are aimed at finding inexpensive materials that can be converted into nanostructured carbon-containing materials, such as activated carbon and graphene. Rice husks are one such material, especially in developing countries, where more than 95% of Rice husks are produced worldwide. Although numerous studies have been conducted on the production of activated carbon and graphene structures from Rice husk, the existing scientific information is still widely scattered in the literature. Therefore, this review article provides extensive information on made by various researchers, including the Institute of combustion problems (Almaty, Kazakhstan), regarding the production of nanostructured carbon-containing materials from rice husk and its adsorption characteristics. The properties and pre-treatment of rice husk in relation to the production of activated carbon and multilayer graphene are discussed. The activation of rice husk by physical and chemical methods under different conditions is considered.
