Characterizing Solid–Liquid Interactions in a Mesoporous Catalyst Support Using Variable-Temperature Fast Field Cycling NMR

Autor: Mick D. Mantle, Lynn F. Gladden, Jean-Pierre Korb, Andrew J. Sederman, Jordan Ward-Williams, Laura Rozing

Publikováno v: The Journal of Physical Chemistry C. 125:8767-8778

Variable-temperature fast field cycling NMR measurements are used to probe the surface dynamics of different liquids imbibed within a γ-alumina catalyst support material. The imbibed liquids were g...

A simple liquid state 1H NMR measurement to directly determine the surface hydroxyl density of porous silica

Autor: Andrew P. E. York, Michael D. Mantle, Petr Steiner, Andrew J. Sederman, Lynn F. Gladden, Marian Bentley, Callum Penrose

Publikováno v: Chemical Communications. 57:12804-12807

Silica is widely used in industrial applications and its performance is partially decided by its surface hydroxyl density αOH. Here we report a quick, simple liquid 1H NMR method to determine αOH using a benchtop 1H NMR spectrometer. The results sh

Experimental Determination of H2 and CO Diffusion Coefficients in a Wax Mixture Confined in a Porous Titania Catalyst Support

Autor: Lynn F. Gladden, Qingyuan Zheng, T. A. Baart, Constant M. Guedon, Andrew J. Sederman, Jack Williams, Mick D. Mantle

Publikováno v: The Journal of Physical Chemistry B. 124:10971-10982

The ability to measure and predict molecular diffusion coefficients in multicomponent mixtures is not only of fundamental scientific interest but also of significant relevance in understanding how catalytic processes proceed. In the present work, the

Insights into Automotive Particulate Filters using Magnetic Resonance Imaging : Understanding filter drying in the manufacturing process and the effect of particulate matter on filter operation and fluid dynamics

Autor: E.H. Stitt, Nicholas P. Ramskill, Athanasios Tsolakis, A.P.E. York, Jonathan D. Cooper, Andrew J. Sederman, Lynn F. Gladden

Publikováno v: Johnson Matthey Technology Review. 64:165-179

Understanding the manufacture and operation of automotive emissions control particulate filters is important in the optimised design of these emissions control systems. Here we show how magnetic resonance imaging (MRI) can be used to understand the d
