✦ Synopsis

Abstract

A highly crystalline ZSM‐5 product was obtained from diatomite, a natural raw material, both with and without the presence of diethanolamine. The synthesis process took 40 h, and was carried out under hydrothermal conditions, at autogenic pressure, and at a temperature of 180 °C. The resulting crystals were identified as ZSM‐5 by X‐ray diffraction and characterized by scanning electron microscopy, infrared spectroscopy, thermal gravimetry and differential thermal analysis.

## Abstract BACKGROUND: This study investigated the synthesis of magadiite from a natural diatomite material. The influence of key reaction parameters, including reaction time, temperature and molar ratios of Na~2~O/SiO~2~ and H~2~O/Na~2~O, on the formation of magadiite were investigated. The as‐sy

## Abstract Mesoporous materials were obtained from two natural silica sources, diatomite and pumicite, under hydrothermal conditions, autogenic pressure and in presence of the surfactant cetyltrimethylammonium bromide (CTAB) as the template. Using diatomite, a temperature of 383 K and the followin
