Mesoporous MCM-41 material
can be synthesized using a variety of silica precursors, but a major
drawback of these precursors is the high production cost of the raw
material (Halina and Ramesh, 2007). In order to enlarge the field of
applications, there is a need for further improvements of composite
molecular sieves with Si in the framework (Li et al., 2010). An alternative
silica source is the waste solar panel that is found in TFT-LCD or
solar panel companies. With
