Micro-porous superlattice separations

摘要

A high surface area substrate with controlled pore size and slot geometry is used in an adsorbing process. The material is made by depositing at least two materials in alternating layers. The film is then broken up and one of the materials is etched away to produce a slotted surface structure. These slots can add size and shape selectivity to separations and catalytic processes which because of the uniform and controllable dimensions (>5A) would be superior to that obtainable from zeolites and clays.
