چکیده
|
Nano-cufe2o4 catalysts with different cu/fe molar ratios (cunfemo(n+1.5m)) were prepared by hydrothermal method. the thermal decomposition performance of cunfemo(n+1.5m) on cuso4 were determined with tg-dsc method to evaluate its catalytic activity and the roasted product was characterized by xrd. the results showed that cunfemo(n+1.5m) had superior catalytic properties and efficiency to cuso4 crystals in 1: 1 cu/fe molar ratios and 4% cunfemo(n+1.5m) (in mass) contained. under these conditions, the high and low temperature decomposition peaks of cuso4 were overlapped. the temperature and heat of decomposition were decreased by 29.5oc and 112.1 j/g, respectively. the results were also confirmed by roasting experiments of cuso4·5h2o in muffle furnace in the presence of cunfemo(n+1.5m) as catalyst at the same temperature
