摘要
In the present communication,the electrooxidation of trioxane(1,3,5-trioxane) was studied as a new fuel for direct-oxidation-type fuel cells. Direct-oxidation-type fuel cells have attracted much attention in recent years for the potential application as portable power sources;it can convert energy directly to electrical energy with high efficiency and low emission of pollution.Trioxane is a solid and favors the logistics of safe transportation as a fuel.The electro-oxidation and electro-sorption characteristics of this fuel at platinum electrode were investigated with electrochemical methods. The cyclic voltammetric result suggests that the electro-oxidation processes occur via chemisorption steps followed by surface reactions of adsorbed intermediates.The rate of electro-oxidation changed with the change of concentration of trioxane,acidity and temperature.The electro-oxidation of trioxane is carried out by an acid-catalyzed hydrolysis step in sulfuric acid solutions.

Trioxane is a solid and favors the logistics of safe transportation as a fuel. The electro-oxidation and electro-sorption characteristics of this fuel at platinum electrode were investigated with electrochemical methods. The cyclic vohammetric result suggests that the electrooxidation processes occur via chemisorption steps followed by surface reactions of adsorbed intermediates. The rate of electro-oxidation changed with the change of concentration of trioxane, acidity and temperature. The electro-oxidation of trioxane is carried out by an acid-catalyzed hydrolysis step in sulfuric acid solutions.
