General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

Application

Activated charcoal, acid-washed with hydrochloric acid forms a composite with natural cellulose, which can be used in the fabrication of a flexible electrode with a specific capacitance of ~103 Fg-1 for supercapacitor application. It can also be used in the preparation of ultracapacitors with asymmetric configuration.
Used in a wide variety of biochemical and immunological applications to remove reactants and waste products.
