Abstract

The structure and electrochemical properties of the products of the thermochemical transformation of aspen modifi ed and unmodifi ed with zinc chloride have been studied. It is shown that the addition of ZnCl2 to the lignin-cellulose mass leads to a signifi cant increase of the specifi c surface area of the carbonized product up to 1800 m2.g-1 and the formation of ZnO crystalline phase. The infl uence of the conditions of material synthesis and electrolyte concentration (1M and 3M KOH) on the shape of voltammetric curves is revealed by cyclic voltammetry. It is established that aspen wood after prolonged exposure in water can be successfully used to produce porous carbon electrode materials
