Autor: Larry P. Haack, Mark Jagner, Kevin A. Dahlberg, Chang Yup Seo, Jason Aaron Lupescu, Sabrina L. Peczonczyk, Johannes W. Schwank, Kevin James Rhodes, Galen B. Fisher

Publikováno v: Applied Catalysis B: Environmental. 183:343-360

The performance of automotive three-way catalysts (TWC) deteriorates with time, temperature and aging environment. Engine control methods are needed to minimize the extent of catalyst deactivation and provide an environment capable of partially redis

Two physical vapor deposition (PVD) processes, magnetron sputtering (MS) and arc plasma deposition (APD), were investigated to prepare oxygen reduction reaction (ORR) catalysts for proton exchange membrane fuel cells (PEMFCs). The catalysts are compo

Characterization of gasoline soot and comparison to diesel soot: Morphology, chemistry, and wear

Autor: Larry P. Haack, Dairene Uy, Monica A. Ford, Alex Sammut, Jon Hangas, Douglas T. Jayne, Mark Jagner, Arup Gangopadhyay, Ann E. O׳Neill

Publikováno v: Tribology International. 80:198-209

Soot from gasoline turbocharged direct injection (GTDI) engines and diesel engines, from exhaust and extracted from oil, were characterized by XRF, XPS, Raman spectroscopy, HRTEM, and Soxhlet extraction followed by GC–MS. Laboratory wear tests with

Nature of the two-step temperature-programmed decomposition of PdO supported on alumina

Autor: Xiaoyin Chen, Johannes W. Schwank, Robert Walter Mccabe, Mark Jagner, Xiaoqing Pan, George W. Graham, Yisun Cheng, Galen B. Fisher, Michael B. Katz

Publikováno v: Applied Catalysis A: General. 475:420-426

Temperature-programmed decomposition of PdO supported on high-surface-area alumina occurs in a two-step process starting near the temperature of bulk PdO decomposition, but slowing to near-zero rates as the bulk oxide decomposition temperature is tra
