High-Throughput Zeolite Membranes
In an invited Perspective (Science, 334, p.767 (2011)), Michael Tsapatsis discusses an emerging new methodology to fabricate ultrathin (few nanometer thick) molecular sieve membranes. This technology appears now feasible due to several notable developments demonstrated by his research team and collaborators: control of preferential orientation (Science, 300, p. 456 (2003)) , elimination of grain boundary defects (Science, 325, p. 590 (2009)) and synthesis of nanosheet seed crystals (Science, 333, p. 72 (2011)). Commercialization of this technology could lead to significant energy savings in the chemical process industry.
A recent talk describing the development of this technology and challenges ahead can be found at:
