WebTEM Description About MCM-41: MCM-41 is an amorphous silica with a regular mesopore system which consists of an array of unidimensional and hexagonally shaped meso-pores. The pore size of the MCM-41 can be controlled from 1.5 to 10 nm by use of an appro-priate surfactant as a template. Web9 Jul 2024 · Fig. 1a was the TEM image of pure MCM-41; the size of the spheroid silica was around 300 nm. Fig. 1b was the TEM image of MoM-2.0; the pore channel can be seen …

WebTEM images of MCM-41 and aminopropyl functionalised MCM-41: (a) calcined MCM-41; (b) extracted MCM-41; (c) direct-NH2-MCM-41; (d) post-NH2-calcined MCM-41; (e) post-NH2 … WebThe DSC curve of MCM-41-A exhibits a straight line, corresponding to its intrinsic thermal stability. MCM-41-B indicates the straight line followed by slope. That can be due to absence of phase transitions and mesoporosity. MCM-41- A MCM-41- A Fig. 1: SEM images of MCM-41-A.
