Catalysis Sans Catalyst Loss: The Origins of Prolonged Stability of Graphene–Metal–Graphene Sandwich Architecture for Oxygen Reduction Reactions

Autor: Ali Abdelhafiz, Ji Il Choi, Bote Zhao, Jinwon Cho, Yong Ding, Luke Soule, Seung Soon Jang, Meilin Liu, Faisal M. Alamgir

Publikováno v: Advanced Science, Vol 10, Iss 34, Pp n/a-n/a (2023)

Abstract Over the past decades, the design of active catalysts has been the subject of intense research efforts. However, there has been significantly less deliberate emphasis on rationally designing a catalyst system with a prolonged stability. A ma

Cooperativity in the Aldol Condensation Using Bifunctional Mesoporous Silica–Poly(styrene) MCM-41 Organic/Inorganic Hybrid Catalysts

Autor: Jacob W. Cleveland, Ji Il Choi, Ryoh-Suke Sekiya, Jinwon Cho, Hyun June Moon, Seung Soon Jang, Christopher W. Jones

Publikováno v: ACS Applied Materials & Interfaces. 14:11235-11247

This work explores the efficacy of silica/organic hybrid catalysts, where the organic component is built from linear aminopolymers appended to the silica support within the support mesopores. Specifically, the role of molecular weight and polymer cha

Graphene Nanoribbon Hybridization of Zeolitic Imidazolate Framework Membranes for Intrinsic Molecular Separation

Autor: Eunji Choi, Ji Il Choi, Yong‐Jae Kim, Yeong Jae Kim, Kiwon Eum, Yunkyu Choi, Ohchan Kwon, Minsu Kim, Wooyoung Choi, Hyungjoon Ji, Seung Soon Jang, Dae Woo Kim

Publikováno v: Angewandte Chemie. 134

Zeolitic imidazolate frameworks (ZIFs) are promising for gas separation membrane, but their molecular cut-off differs from that expected from its intrinsic aperture structure because of their flexibility. Herein, we introduced graphene nanoribbons (G

Density Functional Theory Study of Oxygen Reduction on Graphene and Platinum Surfaces of Pt–Graphene Hybrids

Autor: Han Seul Kim, Faisal M. Alamgir, Ji Il Choi, Young-Jun Sohn, Seung Soon Jang, Sung-Dae Yim

Publikováno v: ACS Applied Nano Materials. 4:1067-1075

Based on recent studies, an epitaxial monolayer of Pt on graphene yielded an enhanced catalytic activity with unprecedented stability resulting in an improved catalyst lifetime. We showed that the ...
