CATALYTIC MATERIALS
Description
Sawyer Technical Materials, LLC has recently adapted our hydrothermal crystal growth technology to the synthesis of a variety of materials used in catalysis. This technology can be uniquely applied to the production of materials enabling the targeted control of the type, location, density, and accessibility of catalytic sites within a given material to a degree very difficult, if not impossible, to achieve by other synthesis techniques. These product advancements are all uniquely application-specific and will require a close collaboration with clients. We have already successfully produced a wide variety of inorganic catalytic materials using this technique. Our recent spectacular successes in commercial development of catalytic materials include:High-purity a -alumina supports with tailored surface area, pore volume and pore size distributions
Nanosized zinc oxide powders with controlled morphology and superior defect structure
Zeolites L, NaP1, beta, mordenite, ZSM-5, and others
High purity a -alumina powders with a broad variety of sizes, morphologies (incl. fibers), and chemical compositions (dopants)
a -alumina/ transition aluminas compositesSpecialty aluminas, i.e. a -alumina/boehmite composite powders
Wide range of metal oxides and metal aluminates (ZnAl2O4, etc)

Frequently Asked Questions
Hydrothermally synthesized zinc aluminate spinel powders have a variety of applications, including as transesterification catalysts and catalytic supports/carriers.
Sawyer Technical Materials has successfully produced a wide variety of inorganic catalytic materials using this technique, including high-purity a-alumina supports, nanosized zinc oxide powders, and zeolites L, NaP1, beta, mordenite, ZSM-5, and others.
Hydrothermal growth technology offers low synthesis temperatures, excellent control of crystallite size and morphology, unique defect structure, high purity, and one-step processing with limited or no required high-temperature annealing and/or milling.
Sawyer's hydrothermally synthesized zinc aluminate spinel powders exhibit much more uniform crystallite size distributions, significantly higher chemical purity, and level of lattice perfection than commercially available powders. Their catalytic performance is superior to the commercial ZnAl2O4 powders, making them attractive biodiesel catalysts.
Hydrothermal crystal growth technology is a method of synthesizing materials used in catalysis that enables the targeted control of the type, location, density, and accessibility of catalytic sites within a given material.
