Current Research Programs:

Our research is directed towards the investigations of inorganic porous materials including zeolites, AlPO4 molecular sieves, pillared lamellar solids and mesoporous materials such as MCM-41. Zeolites are framework aluminosilicates with well defined pore and channel structures, widely used in industry as ion exchangers, molecular sieves, and catalysts. Current efforts emphasize vibrational and solid-state NMR spectroscopy

Research Projects

(1) host-guest interactions in zeolitic systems including: studying the sorbate-induced phase transitions in zeolitic framework; probing the locations of the guest species inside zeolites; examining the dynamic and conformational properties of the sorbate molecules; and investigating the cation-sorbate interactions.
(2) surface mediated reactions of organometallic complexes.
(3) crystallization of microporous and mesoporous molecular sieves.
(4) characterization of layered silicates and pillared layered materials.
(5) effects of high pressure on zeolitic structure.
(6) ionic conductivity of zeolites under high external pressure (in collaboration with Dr. R. A. Secco).
(7) solid-state ion exchange and salt occlusion in zeolites.
(8) preparation and characterization of metal-chalcogenide cluster/MCM-41 composite materials (in collaboration with Dr. J. F. Corrigan).

Our vibrational facility includes a new Bruker RFS 100/S stand alone FT-Raman spectrometer equipped with a Nd:YAG laser operating at a wavelength of 1064.1 nm and liquid nitrogen cooled Ge detector. It has variable temperature capability. An FT-Raman microscope will soon be attached to the existing Raman bench. We also have a Bomem MB-100 FT-IR spectrometer equipped with a DTGS detector. The lab has two diamond anvil cells for high pressure vibrational study.

Our group is the major user of the departmental new 400 MHz solid-state NMR spectrometer. Our new facility includes a Varian/Chemagnetic Infinity Plus console equipped with three RF channels. We have two H/X/Y (a 9.5-mm and a 7.5-mm) triple tuned MAS probes, a 2.5-mm H/X fast spinning probe and a H/X wideline probe.

We also have access to powder XRD, XRF, XPS, SEM, ICP, UV-Vis with diffuse reflectance attachment and TGA/DTA analyzer within the department or on UWO campus.
