Dario Stacchiola

Dario Stacchiola is a tenured Group Leader in the Interface Sciences/Catalysis group at Brookhaven National Laboratory's Center for Functional Nanomaterials. Granted tenure in 2016, he leads research focused on understanding structure-reactivity relationships in catalysis through in-situ characterization techniques. His work bridges fundamental surface science with practical applications in energy conversion and catalytic processes. He maintains dual affiliations as Faculty at Stony Brook University in both the Chemistry Department and Materials Science and Chemical Engineering program.

Dr. Stacchiola's academic foundation includes:

• Ph.D. in Physical Chemistry from University of Wisconsin-Milwaukee (2002)
• B.S. in Physics with specialization in Surface Science from Universidad Nacional de San Luis, Argentina (1996)
• Humboldt Research Fellowship at Fritz-Haber-Institute, Max-Planck-Society (2005-2007)

His pioneering research employs well-defined model catalysts to characterize systems at molecular and atomic levels using complementary in-situ ambient pressure spectroscopy and microscopy. This approach captures dynamically generated active phases and adsorbed surface species that only exist under actual reaction conditions, effectively bridging the 'pressure gap' between traditional ultra-high vacuum studies and real-world catalytic environments. His discoveries include high-activity catalysts based on inexpensive materials showing unprecedented activity at oxide-oxide and metal-oxide interfaces.

Analysis of Stacchiola's publication trajectory reveals consistent advancement from fundamental surface science toward increasingly sophisticated in-situ methodologies. Key themes across his work include oxide catalyst characterization, metal-oxide interface phenomena, 2D material applications in catalysis, and noble gas trapping in nanostructures. His research demonstrates methodological evolution from traditional surface analysis to real-time observation of catalytic processes under operational conditions, with growing emphasis on energy-related applications.

Dr. Stacchiola's scientific contributions have been recognized through prestigious awards:

• Fulbright Award (2021) for international research collaboration
• Humboldt Research Fellowship (2005) for postdoctoral excellence

Stacchiola has pioneered advanced instrumentation for catalytic studies, commissioning an ambient pressure scanning tunneling microscope system and collaborating to adapt ambient pressure x-ray photoelectron spectroscopy instruments from NSLS to NSLS-II. His DOE-funded research has yielded significant discoveries in catalysis science with direct applications for energy conversion and fuel synthesis technologies, including breakthroughs in CO2-to-methanol conversion and noble gas trapping.

As Group Leader of the Interface Science and Catalysis group, Stacchiola directs a multidisciplinary team developing cutting-edge techniques to observe catalysts in action. Current research directions include studying atomic defect lines that suppress iron oxide catalyst deactivation, optimizing coatings on nanowire catalysts, and exploring 2D-(Alumino)Silicate-Noble Clathrates for gas separation applications, positioning his work at the forefront of next-generation catalytic materials development.
