There has been rapid growth in research on catalysis by supported single metal atoms. The interest stems from the highest achievable dispersion of the metal and the highly tunable metal-support interaction, giving single metal atoms unique catalytic properties. Within the class of supported single metal atom catalysts, there are distinct types of catalyst, for example: isolated atoms on a metal oxide support, isolated atoms on a second metal nanoparticle – the so-called single atom alloys, and supported molecular complexes possessing high structural uniformity. Synchrotron-based X-ray absorption and emission spectroscopies are critical to access the structural and chemical information of these materials due to the low metal content and the absence of long-range order. In this workshop, we will cover the current challenges and future prospects in this expanding field with focus on synchrotron-based characterization methods.

Public Lecture | Catalysis: the Hidden Path to Foods, Fuels and Our Future

Simon Bare, January 30, 2018

The high standard of living we enjoy today is made possible by catalysts ­– behind-the-scenes agents that promote chemical reactions in the vast majority of industrial processes, including production of fertilizers, gasoline and other essential products. But we have only a poor understanding of how catalysts actually work. At SLAC's Stanford Synchrotron Radiation Lightsource (SSRL), we are using X-rays to watch catalysts in action at an atomic scale. By observing catalytic reactions in experimental chambers under conditions that mimic large-scale commercial processes, we gain fundamental insights with great practical value for designing industrial catalysts that are more specific and more powerful.
