MemPro has developed unique catalytic products that provide extraordinary benefits to customers. Since our catalyzed nanofiber materials have large surface-area-to-mass ratios, and because of our ability to evenly disperse catalyst nanoparticles along the surface of the fibers, a significant reduction in catalyst usage can be realized to achieve the same chemical conversion efficiency.
We do not use traditional methods to coat our materials with catalysts. Rather, we use a proprietary process – combining one molecule to another to form small catalyst particles on the internal and external surfaces of each nanofiber, leading to a number of beneficial characteristics. For example, small catalyst particles in a diameter range of 1-10 nanometers, which are supported by inorganic nanofibers, are not subject to severe agglomeration (thermal deactivation) compared to wash-coated ceramics. This leads the benefit of longer catalyst functionality.
MemPro produces catalyzed fibers such as the one pictured to the left. The dark spots are catalyst particles with a size range of 1 to 10 nanometers.
We currently manufacture a variety of catalyzed nanofibers that incorporate noble metals, such as platinum, palladium, and rhodium, into the overall ceramic fiber structure. We can also use a combination of all three noble metals in one fiber material for use in catalytic converters. In fact, our proprietary manufacturing process allows us to incorporate virtually any inorganic catalyst into ceramic nanofibers of different compositions.
In addition to our tailored catalyzed nanofiber products, a number of our base ceramic products act as catalysts without the addition of noble metals. For example, aluminum oxide, zinc oxide, ceria-zirconia, and indium tin oxide fall into this category, and are used in a number of catalytic processes.
