以Ｙ 型分子筛为主体，采用气相沉积法制备了分子筛封装ＳｎＯ２ 纳米半导体材料，并通过Ｘ 射线衍射、ＩＲ 吸收光谱、紫外漫反射光谱、ＴＥＭ 等手段对不同条件下制备的样品进行了表征。对于钠型的Ｙ 型分子筛来说，几乎无法实现有效沉积，而以交换处理后的Ｙ 型分子筛为主体，则可以在合适的条件下，能够获得高分散的ＳｎＯ２ 物种，并成功地降低了对主体分子筛的破坏程度。 The molecular sieve-encapsulated SnO2 nanomaterials were prepared by vapor deposition method. The samples prepared under different conditions were characterized by X-ray diffraction, IR absorption spectroscopy, UV diffuse reflectance spectroscopy and TEM. For the sodium type Y zeolite, it is almost impossible to achieve effective deposition, and the exchange-treated Y-type zeolite as the main body, you can under appropriate conditions, to obtain highly dispersed SnO2 species, and successfully reduced the right The degree of destruction of the main molecular sieve.
