Silica Nanoaggregates and Organosilicon Complexes and Methods of Forming them from Biomass Materials

Description:

This technology outlines a process for producing silica nanoaggregates by treating biomass, such as rice husks, with an acidic medium and then subjecting it to high-temperature heat treatment. The process yields silica nanoaggregates with an average particle size of less than 10 nm and can be further treated to form porous silica structures with pores ranging from 10 nm to 200 nm in diameter.

Key Advantages:

• Utilizes renewable biomass materials, offering a sustainable source of silica.
• Produces silica nanoaggregates with controlled particle size and porosity.
• Flexible process parameters (temperature and time) allow for customization of material properties.
• Can produce both non-porous and porous silica structures for varied applications.

Problems Solved:

• Reduces dependency on non-renewable resources for silica production.
• Addresses the challenge of controlling nano-scale features in silica materials.
• Offers a cost-effective and environmentally friendly method for silica synthesis.

Market Applications:

• Filtration and separation technologies.
• Catalysts and catalyst supports.
• Drug delivery systems.
• Advanced composites and coatings.
• Energy storage and conversion devices.
