This discovery also reveals a way to reduce the temperature of the catalytic process. In turn, this reduces the amount of carbon dioxide released. Carbon dioxide accounts for almost 80% of greenhouse gas emissions in the United States. Additionally, this research gives a glimpse into the reactivity achievable with other low-cost metals in the catalytic conversion of propane into propylene.
They also found that the silicon nitride support enabled catalysis in a way that’s faster and more energy efficient than with traditional metals on silica. As a catalyst support, silicon nitride can enhance chemical reactions on the surface of metals relative to more traditionally used oxides. The scientists achieved catalytic conversion of propane at a temperature of 842 degrees F. This is slightly lower than the 1,022 degrees F typically required for catalysis using traditional materials.
Argonne researchers also collaborated with Frédéric Perras, a scientist at Ames National Laboratory, to gain a better understanding of the structure of the zirconium/silicon nitride catalyst. He used a dynamic nuclear polarization-enhanced nuclear magnetic resonance technique to analyze how silicon nitride reacts with metal sites.
“One person cannot do everything. This is really a team effort, and everyone brought their expertise to the table to achieve this goal,” he said.
