复合微孔和介孔材料是用沸石β纳米颗粒合成的，而不需要结构导向剂来形成介孔。这带来了重要的生态和经济优势。研究了老化纳米粒子溶液冷却方式对复合材料形成的影响。通过氮气吸附表征了材料的孔隙度，通过TGA、DRIFT、XRD和TEM表征了材料的沸石性质，通过EPMA表征了材料的铝含量。所有制备的结构都具有沸石性质。然而，老化种子的冷却方法导致了沸石特征的孔隙度和强度的差异。
Composite micro- and mesoporous materials are synthesized using zeolite Beta nanoparticles without the need for a structure directing agent to form the mesopores. This leads to important ecological and economical advantages. The influence of the way of cooling the aged nanoparticles solution on the formation of the composite materials has been studied. The materials have been characterized towards porosity by N2-sorption, towards zeolitic properties by TGA, DRIFT, XRD and TEM, towards aluminium content by EPMA. All prepared structures possess zeolitic properties. However, the method of cooling down of the aged seeds leads to differences in the porosity and intensity of the zeolitic characteristics.
