Carbon aerogels (CAs)are networks of interconnected structures that offer outstanding properties for many different applications  and they can be fabricated from a wide variety of precursors usually involving three steps of synthesis: gelation, drying and carbonization. [1,2] In particular, they are a promising material for supercapacitors, devices that can offer high energy density and power density together with a long life. [3]

The aim of this work is to propose a facile synthetic route to obtain Carbon aerogel-based supercapacitor electrode made of cellulose purified from rice husk (RH). the use of cellulose to prepare CAs and the use of CAs as supercapacitor electrodes have already been reported, however this work presents a synthetic way that build CAs starting from an agricultural waste material that represents a green and economic pathway to obtain Carbon aerogels. [3,4]

Preliminary results obtained by testing our material as electrode in supercapacitor represent our first step in the application of RH cellulose derived CAs both in supercapacitors and in different electrochemical devices.
