以气相色谱和Mossbauer谱研究了K_3[Fe(C_2O_4)_3)负载在HZSM-5和HY沸石上的性质和热分解。实验表明这两种沸石对负载的K_3[Fe(C_2O_4)_3)有明显的不同作用。K_3[Fe(C_2O_4)_3]/HZSM-5仅部分消失K_3[Fe(C_2O_4)_3]的分解特征,氢气中的还原产物为a-Fe,而K_3[Fe(C_2O_4)_3/HY在500℃时的固相产物为不易还原的高分散体系
The properties and thermal decomposition of K_3 [Fe (C_2O_4) _3) supported on HZSM-5 and HY zeolites were investigated by gas chromatography and Mossbauer spectroscopy. Experiments show that these two zeolites have obvious different effects on the supported K_3 [Fe (C_2O_4) _3). The K_3 [Fe (C_2O_4) _3] / HZSM-5 partially disappeared only partially decomposed K_3 [Fe (C_2O_4) _3], the reduction product of hydrogen was a-Fe and K_3 [Fe When the solid phase product is not easy to restore high dispersion system
