Mesoporous Catalyst Supports

Heterogeneous catalysts are integral to many industries due to the performance that is generated in synthetic processes with their use. These catalysts require supports for mechanical stability to prevent movement of the metal/active sites, which also allow them to be recycled more frequently. Mesoporous materials are good candidates for this purpose. Through determination of relevant properties such as surface area, pore size, and pore volume, following ASTM D4222 and using the Anton Paar Nova gas adsorption analyzer, these properties can be determined and further tailored for each industrial application.


Heterogeneous catalysts play a significant role in industry due to their contribution in:

§  Large-scale synthesis and production of chemicals

§  Improved quality and efficiency in production

Many of these catalysts, especially those based on metals and metal nanoparticles, utilize a mesoporous solid support (pore diameters between 2 and 50 nm) to minimize or prevent the movement of the metal so that it can be recycled and reused. This is appealing to producers because higher throughputs and lower costs in catalyst production can be achieved. In addition, supports increase the available metal/active surface area and stabilize the active species.

The proper mesoporous support must be chosen to complement the catalyst being used. If the improper support is utilized, it can lead to counterproductive results and lower yields. Parameters such as BET surface area, pore size, and pore volume will all influence how effective the mesoporous support will be when used with specific catalytic metals.

The Anton Paar Nova gas adsorption analyzer is an excellent choice for analyzing such materials because it can determine all relevant parameters quickly and precisely.
