Zeolite Socony Mobil-5 (ZSM-5) was successfully synthesized by a hydrothermal method from the silicon dioxide (SiO2) precursor prepared fro m rice husk ash. Titanium dioxide (TiO2) nanoparticles were decorated on ZSM-5 substrate by a sol-gel method. ZSM-5/TiO2 materials were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscope (TEM), and Brunauer-Emmett-Teller (BET) surface area analysis.

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.

The aim of the work "Activated carbon derived from rice husk by NaOH activation and its application in supercapacitor" is to prepare a low-cost, high specific surface area activated carbon with microporous and mesoporous ranges using rice husk as the raw material. The effects of activation temperature on the specific surface area, pore structure, morphology and thermal stability of the AC samples have been examined. The AC samples were proved to be excellent electrode material for supercapacitor, hence solve the disposal and pollution problems of rice husk.

The reactions form chains and rings of alumino-silicate networks in geopolymeric structures. The raw materials used for geopolymerization normally contain high SiO2 and Al2O3 in the chemical compositions such as meta-kaoline, rice husk ash, fly ash, bottom ash, blast furnace slag, red mud, and others. The geopolymer-based material has potentials to replace Ordinary Portland Cement (OPC)-based materials in the future because of its lower energy consumption, minimal CO2 emissions and lower production cost as it utilizes industrial waste resources.
