High temperature efforts at Los Alamos National Laboratory

Description

With the potential for significant payoffs in chemical processing, separation science, and ``green technology``, inorganic membranes merit the increased attention they are currently receiving. Application of thin film deposition and characterization expertise at Los Alamos National Laboratory (LANL) to the fabrication of membranes has led to the development of two new membranes. The first is a zeolitic film formed by pulsed laser deposition (PLD). The material deposited is largely amorphous but yields an interesting microporous structure. The pores, roughly 10 to 15 A in diameter, run perpendicular to the substrate and, since the film is typically only a half micron ... continued below

Description

With the potential for significant payoffs in chemical processing, separation science, and ``green technology``, inorganic membranes merit the increased attention they are currently receiving. Application of thin film deposition and characterization expertise at Los Alamos National Laboratory (LANL) to the fabrication of membranes has led to the development of two new membranes. The first is a zeolitic film formed by pulsed laser deposition (PLD). The material deposited is largely amorphous but yields an interesting microporous structure. The pores, roughly 10 to 15 A in diameter, run perpendicular to the substrate and, since the film is typically only a half micron thick, provide excellent flow rates. The PLD material has been deposited on quartz crystal microbalances (QCMS) to investigate its potential as a sensor. As such, it has shown discrimination of simple alcohol isomers. The second membrane, consisting of a composite metal structure, passes hydrogen exclusively. Currently, we are studying the possibility of incorporating the membrane in a hydrogen fuel cell using a methanol reformer.
