TL;DR: In this article, the mesoporosity development in high silica HZSM-5 was carried out by alkaline desilication treatment and soft template method, and its relationship with the catalytic performance of the modified catalysts in methanol-to-propylene reaction was studied.

TL;DR: In this paper, the authors investigated the catalytic activity of four polymorphs of gallium oxide in the presence or absence of CO 2 and showed that β -Ga 2 O 3 exhibits the highest activity among the polymorphs, and it is even more active than chromium oxide catalyst.

TL;DR: This article reports a controllable and reproducible approach to prepare highly ordered 2-D hexagonal mesoporous crystalline TiO2-SiO2 nanocomposites with variable Ti/Si ratios and shows that the stability of the composites is higher than 900 degrees C.

TL;DR: Monodisperse and high-surface-area mesoporous inorganic spheres of various compositions including metal oxides, mixed oxides and metal phosphates are prepared by templating mesoporus carbon spheres which are replicated from spherical Mesoporous silica due to the rigid and thermally stable framework of carbon template.

TL;DR: In this paper, a modified high silica HZSM-5 catalysts have been used to selectively transform methanol to propylene (MTP) and the enhancement of propylene selectivity and catalytic life can be attributed to partial elimination of the strong acid sites on the HZ SM-5 catalyst.
