In this study, we developed the ammonia sensing material by using MCM-41 impregnated with bromocresol green. MCM-41 is one kind of mesoporous molecular sieves. It can be applied to many fields due to well-defined pore shapes, narrow distribution of pore sizes, large pore volumes, high surface area, excellent thermal, hydrothermal, chemical and mechanical stability. And the bromocresol green dye is commonly used as a pH indicator with colorimetric from pH 3.8 to pH 5.4.

本研究之目的是结合变色染剂及中孔洞分子筛MCM-41进行氨气吸附，研究中所选择之变色染剂溴甲酚绿是一种偏酸性之大分子有机染剂，其变色范围在pH 3.8到pH 5.4；而MCM-41由於其孔洞大小分布范围狭窄、孔洞体积大、高比表面积、具有良好的吸附容积、表面反应性强及易於改质等优点，故期望利用此复合材料，经气体吸附达到氨的移除并同时在吸附饱和前能产生显色效果。
