ABSTRACT:
Methods for forming membranes of semiconductive material incorporating molecular sieve material therein can involve sol gel techniques and suction techniques. The semiconductors, such as metal oxides, sulfides or carbides have photoactivity and are useful in photocatalytic reactions. An example of such a membrane is titanium oxide including zeolite molecular sieve incorporated therein. The membranes can be used to perform useful chemical reactions such as the mineralization of organic chemicals in the presence of light. For example, many toxic organic chemicals can be converted to useful or benign products by contacting those chemicals with active metal oxide-molecular sieve membranes in accordance with the invention and illuminating the membranes with light of a suitable wavelength.
