摘要
考察了酸碱环境对Fe -HMS合成的的影响 ,通过对合成样品的XRD、FT -IR、SEM表征 ,发现在碱性条件下 ,Fe -HMS晶体易于合成 ,并且合成样品的DDA模板效应强、晶体结构稳定、孔体积大、Fe含量高。
Effects of Acid-Base Systems on Fe-HMS synthesis were studied,and synthetic samples were characterized by XRD、FT-IR、SEM,etc.It has been shown that the Fe-HMS Crystalline was easily prepared the strong template effect of DDA.The stable struture、the large pore votume and the high Fe loading were discovered in basic system.
