Practical catalysts with a porous framework, such as zeolites, host catalytic reactions at active sites engrained in the pores and channels of the scaffold. The mechanism of interaction at these active sites, defining catalyst performance, remains el

Polyoxometalates (POMs) featuring 7, 12, 18, or more, redox-accessible transition-metal ions are ubiquitous as selective catalysts, electrocatalysts, and sensitized photocatalysts, especially for oxidation reactions. The corresponding synthetic and c

Pair distribution function analysis of discrete nanomaterials in PDFgui
Autor: Zhihengyu Chen, Michelle L. Beauvais, Karena W. Chapman
Publikováno v: Journal of Applied Crystallography. 56:328-337
Pair distribution functions (PDFs) are a leading tool for atomic structure analysis of nanomaterials. However, the most widely used programs for refining atomic structure against PDF data are based on extended crystallographic models, which cannot be

Node Distortion as a Tunable Mechanism for Negative Thermal Expansion in Metal-Organic Frameworks
Autor: Zhihengyu Chen, Gautam D. Stroscio, Jian Liu, Zhiyong Lu, Joseph T. Hupp, Laura Gagliardi, Karena W. Chapman
Publikováno v: Journal of the American Chemical Society.
Chemically functionalized series of metal-organic frameworks (MOFs), with subtle differences in local structure but divergent properties, provide a valuable opportunity to explore how local chemistry can be coupled to long-range structure and functio

Enhanced Catalytic Performance of a Ce/V Oxo Cluster through Confinement in Mesoporous SBA-15
Autor: Xingjie Wang, Zoha H. Syed, Zhihengyu Chen, J. David Bazak, Xinyi Gong, Megan C. Wasson, Nancy M. Washton, Karena W. Chapman, Justin M. Notestein, Omar K. Farha
Publikováno v: ACS applied materialsinterfaces. 14(47)
To increase catalytic efficiency, mesoporous supports have been widely applied to immobilize well-defined metal oxide clusters due to their ability to stabilize highly dispersed clusters. Herein, a redox-active heterometallic Ce

Understanding heterogeneous catalysts is a challenging pursuit due to surface site nonuniformity and aperiodicity in traditionally used materials. One example is sulfated metal oxides, which function as highly active catalysts and as supports for org

We describe and experimentally illustrate a strategy for synthesizing reactant-accessible, supported arrays of well-confined, sub-nanometer to 2 nm, metal(0) clusters and particles-here, copper, palladium, and platinum. The synthesis entails (a) solu
