Self-Assembled Nanostacking of Nanoporous Materials with Microwave Irradiation and Their Application

초록

Application of a microwave technique to the conventional hydrothermal process is gaining importance, especially, in the synthesis of nanoporous materials. This microwave synthesis is regarded as a novel tool because it gives very unique advantages such as homogeneous nucleation, rapid synthesis, formation of uniform crystals, and small crystallites, facile morphology control, energy efficiency and so on.2 Recently, it was found that it offers an efficient way to control the crystal morphology, size and orientation, and even crystalline phase which are required for many emerging applications of nanoporous materials. The microwave effect, self-assembly of nanoporous materials and control of crystal morphology upon microwave synthesis of nanoporous materials will be discussed. Rapid and uniform synthesis with morphology control of nanoporous materials such as ZSM-5, zeolite beta, metallosilicates, AlPO, MCM-41, SBA-15, SBA-16, etc. have been accomplished with microwave synthesis.3 In particular, the rapid nucleation and crystallization of ZSM-5 zeolite under microwave irradiation made it possible to enable the continuous microwave synthesis, implying a great industrial and technological importance.
