Abstract

In this paper, mesoporous, nano-structured MCM-41 and MCM-48 type catalysts were synthesized by direct hydrothermal synthesis (DHS) and room temperature synthesis (RTS) methods. It was seen for MCM-41 type catalysts that; both DHS and RTS methods were successful yielding catalysts with regular crystalline pore structures. In the case of MCM-48 type catalysts, however, the catalyst produced by the RTS method had significant loss of crystalline pore structure. Investigation of BET results showed that MCM-41 catalysts synthesized by the DHS method and MCM-48 catalysts synthesized by the RTS method had higher surface area and higher pore volume values than their counterparts.

Özet

Bu makalede, mezo-gözenekli, nano-yapılı MCM-41 ve MCM-48 türü katalizörler doğrudan hidrotermal sentez (DHS) ve oda sıcaklığında sentez (OSS) metotları ile üretilmiştir. MCM-41 türü katalizörler için her iki sentez metodunun da başarılı olduğu ve düzgün kristal gözenek yapısına sahip katalizörler üretildiği görülmüştür. MCM-48 türü katalizörlerin sentezinde ise OSS metodu ile sentezlenen katalizörün kristal gözenek yapısının önemli ölçüde bozulduğu görülmüştür. BET sonuçları incelendiğinde, altıgen gözenekli MCM-41 katalizörleri için OSS ve kübik gözenekli MCM-48 katalizörleri için DHS metodunun daha yüksek yüzey alanı ve gözenek hacmi değerleri verdiği tespit edilmiştir.
