The National Science Foundation (NSF) Engineering program (CFDA 47.041) awarded a $299,973 project grant to Oklahoma State University (OSU) to develop pore-engineered membranes using an in situ atomic layer deposition (ALD) process for improved chemical separations. The key research objectives are to: (A) determine the effect of catalytic ALD on curing membrane defects, (B) elucidate the effect of ALD formation of metal oxides on gas selectivity by controlling pore size, and (C) exploit metal ALD to control molecular interactions between metals and gases using electronegativity to enhance permeance. This project aims to uncover principles for designing microporous membranes with precisely controlled pore structures to enable more efficient and cost-effective chemical separations, particularly for challenging olefin/paraffin separations. The award period is from Aug 1, 2024 to Jul 31, 2027. No subawards are planned under this grant.
