Cerafirst™ SBA-15
Ordered Mesoporous Silica
Cerafirst™ SBA-15 is a typical ordered mesoporous silica material featuring a well-ordered two-dimensional hexagonal pore structure and excellent tunable pore size. It is constructed via a templating method to form a stable mesoporous network, ensuring both high specific surface area and good pore connectivity, which significantly enhances mass transport performance.
Product Overview
Cerafirst™ SBA-15 is a typical ordered mesoporous silica material featuring a well-ordered two-dimensional hexagonal pore structure and excellent tunable pore size. It is constructed via a templating method to form a stable mesoporous network, ensuring both high specific surface area and good pore connectivity, which significantly enhances mass transport performance.
Based on nitrogen adsorption–desorption measurements, the sample exhibits a typical small mesoporous structure (~3 nm), accompanied by a small amount of microporosity. This results in a hierarchical pore system that balances adsorption capacity and diffusion efficiency, making it suitable for catalysis, electrochemical applications, and adsorption/separation processes.
