| Abstract: | The current status of activated carbon made from wooden sources by H3PO4 activation is reviewed. The influences of phosphoric acid concentration and heat treatment conditions on the pore size distribution of the products as well as the suitable process conditions for different starting materials have been elucidated. The mechanism involved in the H3PO4 activation process is also addressed. The importance of investigating the mechanism of the ash formation in the H3PO4 activation process is highlighted. |
