Zeolite seed-based mesoporous aluminosilicate material MSU-S is normally synthesized from pure chemicals. In the study, MSU-S material was synthesized using natural resources such as rice husk, and kaolin in Vietnam. Here, a systematic investigation is conducted to find the relationship between the synthesis conditions (aging time, hydrothermal time, hydrothermal temperature, pH environment) and the formation of mesoporous structure, as well as the material properties.

This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.
