Metal-Organic Frameworks (MOF) for decontamination and filtration
Novel Methods for cost-effective MOF Manufacturing
MOFs - Metal-Organic Frameworks
MOFs, or metal-organic frameworks, consist of metal ions or clusters connected by organic molecules called linkers. They form a unique cage-like structure with empty spaces or pores. This allows MOFs to have a large surface area and high porosity, giving them unique properties and potential applications in various fields. The choice of metal ions and organic linkers used in the synthesis of MOFs can be tailored to achieve specific properties and functionalities. This tunability allows MOFs to be engineered for different applications, such as gas storage, separations, catalysis, drug delivery, sensing, and more. Because of this tunability, MOFs have gained significant attention in scientific research and industrial applications. However, large-scale production is challenging, limiting their availability in large quantities.
Tetramer MOF Programs
For the last several years, Tetramer has engaged in several projects made possible by the unique properties of MOF technology. Our team is tackling chemical and biological defense applications in fabrics to protect soldiers and civilians, water purification technologies to remove dangerous heavy metals, and the development of a cost-effective manufacturing process for MOFs used in the reprocessing of spent nuclear fuels.
Our team has gained deep expertise in the area and welcomes further collaborations in this exciting and growing space.

Ongoing MOF Projects
In addition to our proprietary industrial partnerships, the US Department of Defense Joint Science and Technology Office for Chemical and Biological Defense and the US Department of Energy and are funding continued development of Tetramer MOF technologies.
Developing Adsorbent Materials with MOFs: to protect soldiers from chemical warfare agents
Funded by the Department of Defense Joint Science and Technology Office for Chemical and Biological Defense on a 2-year Phase II program, Tetramer’s MOF team is continuing the development of a novel adsorbent material used in protective suits for soldiers that encounter chemical, biological, radiological, and nuclear (CBRN) threats. Tetramer bead technology consists of metal-organic frameworks (MOFs) that are incorporated into garments to adsorb and degrade chemical warfare agents (CWAs) into non-toxic compounds on contact.
For warfighters facing the threat of chemical warfare agents, confidence in protective gear is critical. Heather Lange, Tetramer Research Scientist said, “Tetramer’s material not only adsorbs the chemical threat but degrades it as well, significantly increasing efficacy of the suit to improve the physical safety and the psychological performance of the soldiers. This material has applications in protective suits as well as gloves, boots, and even gas masks.”
Using these beads in place of current materials is expected to better protect warfighters while also increasing breathability and comfort to enable extended use times and reduced logistical burden on forward operating units. Additionally, these materials are suitable for use in protective wear for civilian industrial applications such as HAZMAT suits.

Developing MOF Manufacturing Methods: for cost-effective and continuous production of MOFs
Working under a Department of Energy Phase I award, Tetramer developed a method for the cost-effective syntheses of MOF structures suitable for use in a variety of applications, including nuclear waste separations activities. The Tetramer MOF manufacturing process developed in this program has achieved exceptional results including:
- Greater than 2X increase in yield (%) compared to MOF yields using published synthetic methods
- Space Time Yields (STY) of the MOF Syntheses 8-18X that of published synthetic methods
- Reduced equipment requirements (now compatible with stainless steel)
- Successful recycling of unreacted starting materials to further reduce MOF cost (up to 90% yield with recycled starting materials)
- Xe/Kr uptake and selectivity corresponding to published values

Building on the above successes in Phase I efforts, Tetramer is interested in collaborations to continue the development and optimization of the MOF manufacturing process.
Developing Filtration Materials with MOFs: for selective capture of contaminants and/or valuable metal ions from water
Funded by a Department of Energy Phase II award, Tetramer is working on the development and commercialization of a filtration material that can remove heavy metal toxins from industrial waste streams before they are released into the environment.
As the use of electronics and other technologies that rely on heavy metals has increased, more heavy metal contaminants make their way into our environment. Even in small amounts, contaminants such as lead, mercury, cadmium, arsenic, and chromium can be dangerous to both aquatic life and humans. Current water treatment methods are not selective for these specific dangerous metals, lack operational efficiency, and require frequent replacement when they become overloaded. To overcome these issues, the Tetramer team is working under DOE Phase II funding to develop new tailorable materials that can selectively adsorb and remove toxic heavy metal ions from water.
“Removing contaminants from drinking water is a major problem worldwide. Tetramer’s efforts to produce filter media that are selective to heavy metals will add one more tool for producing clean water and can aid in improving clean water access to millions of people,” said Tetramer CEO, Jeff DiMaio.
