Low-Temperature Catalysts for Effective Reduction of Nitrogen Oxide (NOx) Emissions

34359 – Researchers at the University of Central Florida and BASF Corporation have developed a selective catalytic reduction (SCR) technology that can efficiently remove nitrogen oxide (NO) emissions at temperatures less than 200 degrees Celsius. Nitrogen oxides are major pollutants emitted from internal combustion engines. Examples include gasoline and diesel vehicles and stationary... Read More

Scalable Approach for Fabricating Thermally Stable, Low-Temperature Catalysts

34292 – Researchers at the University of Central Florida have developed a low-cost, scalable approach for using any reducible metal oxide or mixed metal oxide materials to fabricate thermally stable, low-temperature catalysts. The UCF invention offers a solution for automakers tasked with meeting increasingly stringent emissions standards. For example, future catalytic systems will need... Read More

As shown in the example, at least a portion of the precious metal (PGM–platinum group metal) encapsulated between the base material and the irreducible metal oxides may be shuttled to the surface of the metal oxide to form stable, catalytically active sites that can resist sintering at high temperatures.

Low-Cost Method for Producing Highly Stable, Active Precious Metal Catalysts

34303 – Researchers at the University of Central Florida have developed a novel universal technique for fabricating precious metal catalysts that exhibit both high catalytic activity and excellent thermal stability. UCF’s Reverse Loading and Metal Shuttling Strategy offers a low-cost solution to traditional fabrication methods, such as those that require complex preparation procedures or... Read More
