| Abstract: | In this work, doped-chitosan samples are prepared by mixing various inorganic oxides and metal nitrates with chitosan. Thermal cracking processes of these samples are investigated by thermal analysis method. By compa- ring the initial decomposition temperature, maximum decomposition temperature and final decomposition tempera- ture derived from thermal analysis curves of doped-ehitosan, it is found that doping vanadium oxide, copper nitrate or nickel nitrate to chitosan can obviously accelerate thermal cracking process of ehitosan and decrease its thermal decomposition temperature. These compounds are good catalysts to produce hydrogen by chitosan decomposition. |
