Abstract: The past decade or so have seen a number of technological advances in the field of transmission electron microscopy that have dramatically enhanced both the utility and utilization of the instrument in the field of heterogeneous catalysis. These include aberration correction, enhanced detectors and improvements in simulation and analysis software. In this presentation, I will present several specific examples from both my own research and from others in the field to provide a general overview of the state of the art. In specific, I will describe the limits of spatial, spectroscopic and temporal energy resolution, and demonstrate how one can perform both real time and operando measurements do characterize the interrelationships between catalyst structure and catalyst function. Through the presentation, I will emphasize how these techniques are being implemented at the Singh Center for Nanotechnology at the University of Pennsylvania and how they are thus accessible to members of the Catalyst Club of Philadelphia.

Abstract: Hydrodesulfurization catalysts have two types of active sites for hydrogenation and hydrogenolysis reactions. While hydrogenation sites are more active for desulfurizing refractory sulfur species, they are more vulnerable to organonitrogen inhibition than hydrogenolysis sites. In contrast, hydrogenolysis sites are less active for desulfurizing refractory sulfur species but are more resistant to organonitrogen inhibition. This dichotomy is exploited to develop an ultra-deep hydrodesulfurization stacked-bed reactor comprising two catalysts of different characteristics. The performance of this catalyst system can be superior or inferior to that of either catalyst alone. A theory is developed to predict the optimum stacking configuration for maximum synergies between the two catalysts. The best configuration provides the precise environment for the catalysts to reach their full potentials, resulting in the smallest reactor volume and maximum energy saving. Model predictions are consistent with experimental results. A selectivity-activity diagram is developed for guiding the development of stacked-bed catalyst systems.

Abstract: Iridium complexes have played a leading role in the organometallic chemistry of
alkanes and unreactive C-H bonds since the inception of the field 30 years ago. We have found
that “PCP”-pincer-ligated iridium complexes are particularly effective for the dehydrogenation of
alkanes and have incorporated this reaction into tandem systems for several catalytic
transformations based on dehydrogenation. A closely related class of reactions that we are
exploring is dehydrogenative coupling. More recently we have turned attention to iridium
Phebox complexes. Although the (PCP)Ir and (Phebox)Ir units are formally isoelectronic, the
former operates via C-H activation by Ir(I) while the latter effects dehydrogenation via Ir(III) (as
an acetate complex) and possibly Ir(V) intermediates. Such a high-oxidation-state catalytic cycle
offers advantages for many potential applications of dehydrogenation. In parallel, however, we
find that the low-oxidation-state (+I) chemistry of (Phebox)Ir offers its own novel hydrocarbon

It is my distinct pleasure to welcome all of you to the 2018–19 season of the Catalysis Club of Philadelphia on behalf of the Club’s Officers. The Club’s program will kick off this year with a presentation by Prof. Alan Goldman on September 27th, 2018. Due to the availability of our Catalysis Club of Philadelphia Award Recipient, Dr. Carmo Pereira, the CCP Award lecture will be given on January 17th, 2019. The speaker schedule for the 2018–19 season (put together under the coordination of Srinivas Rangarajan from Lehigh University), along with the special events, is listed below. We hope that you’ll join us and that you’ll enjoy the planned talks!

The monthly meeting location will remain the same and will be held at the Crowne Plaza Hotel in Claymont, DE (630 Naamans Road, Claymont, DE 19703). In order to offset rising catering costs, meeting fees have increased to $40.00 for members, $25.00 for students/retirees, and will include one drink during the social hour. The fees for walk-ins and non-members will be $45.00. We strongly encourage you to register for the meeting using the online registration form, a link to which is provided in each meeting announcement email.
Reservations can also be made by contacting our Treasurer (Lifeng.Wang@pqcorp.com) or Chair (Eric.R.Sacia@dupont.com) directly. Dues for the 2018–19 season will remain at $25.00 ($5.00 for the local club and $20.00 to the national club). Dues for students, postdocs and retirees will be $10.00 ($5.00 for the local club and $5.00 to the national club).
Our annual student poster competition (organized by Nick McNamara of Johnson Matthey) will be held on November 15th, 2018. It provides an important forum for local students to disseminate their work and interact with fellow scientists from industry and academia. Furthermore, selected students from local universities will also be given the opportunity to provide a brief presentation of their work at certain meetings.
Feel free to contact either myself or the other officers with any comments or questions, and keep checking our website periodically (www.catalysisclubphilly.org) for news or updates. Looking forward to seeing all of you this season!
