Research Interests

Professor Falconer's research focuses on inorganic membranes, heterogeneous catalysis, and applications of atomic and molecular layer deposition to catalysts and membranes. Our laboratory has published more than 230 papers in refereed journals, and these papers have been cited more than 10,300 times (h-index = 57 on ISS Web of Science). In addition, 19 patents have been issued from our research, and more than 20 patent applications are pending.

Zeolite membranes
Professors Rich Noble, Hans Funke, and I are studying inorganic membranes for both gas and liquid separations. This research is concentrated on zeolite membranes for CO2/CH4 separations at pressures up to 70 bar. This separation is of interest because many natural gas wells are contaminated by CO2. The SAPO-34 membranes we have prepared have high selectivities and high fluxes. We have also scaled-up these membranes to longer lengths and to multichannel monoliths. We used a technique that can obtain spatial flux maps to understand defects and how they affect separation. These membranes can separate CO2/i-butane by molecular sieving with selectivities in the hundreds of thousands.

MLD-modified membranes
We are using molecular layer deposition (MLD) to prepare membranes with high selectivities for hydrogen separation. These membranes have been shown to be selective at high pressures and elevated temperatures and to have high fluxes. MLD layers are extremely thin, and such membranes have the potential to have dramatically higher fluxes than other types of membranes.
Heterogeneous catalysis
In collaboration with Professors Will Medlin and Alan Weimer, we are studying the application of atomic layer deposition (ALD) and molecular layer deposition (MLD) to high surface area catalysts. These techniques are being used to modify catalysts to change selectivity, create new types of catalysts, and increase catalytic stability.

Educational Interests

Professor J. Will Medlin, Dr. Janet DeGrazia, Dr. Garret Nicodemus and I have developed a library of 1,600 ConcepTests and more than 1,300 screencasts for chemical and biological engineering courses ( This continuing effort is supported by the National Science Foundation, the University of Colorado Engineering Excellence Fund, and Shell. These screencasts were watched/downloaded more than 2.8 million times in the last twelve months. We have also developed course packages for thermodynamics and material and energy balance courses that incorporate active learning.

I have directed the development of more than 90 interactive Mathematica simulations that are on
