Methane Activation by a Mononuclear Copper Active Site in the Zeolite Mordenite: Effect of Metal Nuclearity on Reactivity

Autor: Alexander J. Heyer, Dieter Plessers, Augustin Braun, Hannah M. Rhoda, Max L. Bols, Britt Hedman, Keith O. Hodgson, Robert A. Schoonheydt, Bert F. Sels, Edward I. Solomon

Publikováno v: J Am Chem Soc

The direct conversion of methane to methanol would have wide reaching environmental and industrial impact. Copper containing zeolites can perform this reaction at low temperatures and pressures at a previously defined O(2) activated [Cu(2)O](2+) site

Publikováno v: Chem Rev

Transition-metal-exchanged zeolites perform remarkable chemical reactions from low-temperature methane to methanol oxidation to selective reduction of NOx pollutants. As with metalloenzymes, metallozeolites have impressive reactivities that are contr

Tuning Copper Active Site Composition in Cu-MOR through Co-Cation Modification for Methane Activation

Autor: Dieter Plessers, Alexander J. Heyer, Hannah M. Rhoda, Max L. Bols, Edward I. Solomon, Robert A. Schoonheydt, Bert F. Sels

Publikováno v: ACS Catal

The industrial implementation of a direct methane-to-methanol process would lead to environmental and economic benefits. Copper zeolites successfully execute this reaction at relatively low temperatures, and mordenite zeolites in particular enable hi

Spectroscopic Definition of a Highly Reactive Site in Cu-CHA for Selective Methane Oxidation: Tuning a Mono-μ-Oxo Dicopper(II) Active Site for Reactivity

Autor: Alexander J. Heyer, Bert F. Sels, Robert A. Schoonheydt, Hannah M. Rhoda, Edward I. Solomon, Dieter Plessers, Max L. Bols

Publikováno v: J Am Chem Soc

Using UV-vis and resonance Raman spectroscopy, we identify a [Cu2O]2+ active site in O2 and N2O activated Cu-CHA that reacts with methane to form methanol at low temperature. The Cu-O-Cu angle (120°) is smaller than that for the [Cu2O]2+ core on Cu-

Selective Formation of alpha-Fe(II) Sites on Fe-Zeolites through One-Pot Synthesis

Autor: Edward I. Solomon, Dieter Plessers, Max L. Bols, Hannah M. Rhoda, Michiel Dusselier, Robert A. Schoonheydt, Julien Devos, Bert F. Sels

α-Fe(II) active sites in iron zeolites catalyze N2O decomposition and form highly reactive α-O that selectively oxidizes unreactive hydrocarbons, such as methane. How these α-Fe(II) sites are formed remains unclear. Here different methods of iron

Atmospheric methane removal: a research agenda

Autor: Jennifer Wilcox, Hannah M. Rhoda, Kirsten Zickfeld, Sabine Fuss, Edward I. Solomon, Renaud de Richter, Chris D. Jones, Josep G. Canadell, Chaopeng Hong, Steven J. Davis, Sam Abernethy, Robert B. Jackson, Maxwell Pisciotta, Fiona M. O'Connor, Matteo Cargnello, Sarah Feron, H. Damon Matthews, Alexander J. Heyer

Atmospheric methane removal (e.g.in situmethane oxidation to carbon dioxide) may be needed to offset continued methane release and limit the global warming contribution of this potent greenhouse gas. Because mitigating most anthropogenic emissions of

Advances in the synthesis, characterisation, and mechanistic understanding of active sites in Fezeolites for redox catalysts

Autor: Kristine Pierloot, Edward I. Solomon, Robert A. Schoonheydt, Max L. Bols, Benjamin E. R. Snyder, Hannah M. Rhoda, Bert F. Sels

The recent research developments on the active sites in Fe-zeolites for redox catalysis are discussed. Building on the characterisation of the α-Fe/α-O active sites in the beta and chabazite zeolites, we demonstrate a bottom-up approach to successf

Fencing in radicals Zeolite catalysis could potentially offer a more direct route from methane to methanol. However, current catalysts tend to deactivate too quickly for practical use. Snyder et al. investigated the deactivation mechanism using Möss
