Andrew and Mark join the group!
Two new first year students from the Chemical Engineering PhD program have joined the group! Welcome!!
Simone is awarded a grant from Northwestern’s Office of Undergraduate Research!
Simone is awarded an Academic Year Research Grant (AYURG) from Northwestern’s Office of Undergraduate Research! Her work will investigate modifications of catalyst ink preparation and electrode fabrication to improve durability for electrochemical water oxidation. Congrats Simone!
Brianna, Ruihan, AJ, and Khantey represent Seitz lab with presentations at AIChE Annual Meeting!
Brianna, Ruihan, AJ, Khantey, and Linsey traveled to Phoenix to give oral and poster presentations at AIChE. Senior undergraduate Khantey presented her work at both the AIChE Student Conference and the AIChE Annual Meeting! Congratulations to everyone on their hard work to collect and share these exciting results!
Jane and AJ publish paper describing critical degradation processes for commonly used substrates in electrocatalytic research
Jane’s collaborative paper with AJ highlights that glassy carbon, which is used ubiquitously as a substrate material for electrochemical water oxidation studies, is not electrochemically inert under relevant reaction conditions on the timescale of common stability tests. Critically, this can cause electrodes to exhibit performance losses that do not reflect the intrinsic stability of the actual catalyst material being investigated. In light of our findings, we underscore the usefulness of metrics, such as the S-number, to reflect intrinsic catalyst material stability.
Brianna publishes paper on local electrochemical reaction environment effects in Journal of Catalysis
Brianna’s paper reports on her work developing and applying a pH probe to assess local reaction environment conditions with performance metrics for a carbon catalyst driving oxygen reduction towards production of hydrogen peroxide.
Congratulations Brianna!
Congratulations to Brianna and Jane on receiving travel awards for the ACS Conference in Chicago!
Brianna presented her work in the Industrial and Engineering Chemistry (I&EC) Division Graduate Student Award Symposium and Jane received the CATL-ChemCatBio Graduate Student Travel Award from the Catalysis Science and Technology Division.
Congratulations Ladies!
Matt publishes paper on method to mitigate Pt loss in PEM Fuel Cells in Advanced Functional Materials
Matt is co-first author with Dr. Kyu-Young Park of Professor Hersam’s group on a paper that shares an approach for improving durability and mitigating Pt loss from polymer electrolyte membrane fuel cell cathodes. Graphene nanoplatelets suppress Pt dissolution and agglomeration, while providing defect sites for redeposition of Pt upon cycling to improve performance in accelerated stress tests operated in both diagnostic rotating disc electrode and applied membrane electrode assembly setups.
Congratulations Matt!
Bing publishes paper on novel oxynitride material with exceptional HER activity in JACS
Bing’s paper reports on his work synthesizing a novel oxynitride perovskite material that overcomes significant challenges in stabilizing a late transition metal (Ir) in the presence of nitrogen and oxygen anions. This Ir-incorporated SrW(O,N)3 is also highly active for the hydrogen evolution reaction, surpassing the precious metal mass activity of Pt by 4.5x!
Congratulations Bing!
Simone joins the group!
Simone, a rising sophomore in Chemical Engineering, joins the group! She will be investigating short- and long-term stability of various electrode supports under reaction conditions. Welcome and looking forward to a great summer!
