Improved catalytic enzyme preparations are provided which effectively catalyze reactions carried out in organic solvents. The preparations comprise nanoscale solid support particles (e. g. , fumed silica or alumina) having enzyme molecules electrostatically adhered to the surfaces of the particles. The preparations are prepared by mixing together solid support particles and enzyme molecules in an aqueous system under pH conditions establishing opposite charges on the support particles and enzyme molecules, respectively. The water is then removed from the system, preferably by pre-freezing followed by lyophilization to yield free-flowing, particulate catalyst particles which can be used in liquid organic reactions or in packed bed reactors.

An ultrathin, high-flux composite membrane for use in gas separation. The membrane comprises a metal layer, typically 500. ANG. or less thick on a microporous support. The support may be as asymmetric Loeb-Sourirajan type membrane or a two-layer composite of a microporous substrate with a very thin sealing layer. The support gives mechanical strength to the membrane but does not contribute significantly to the selectivity. Optionally the metal layer may be overcoated with a second polymeric sealing layer to plug any defects and to protect the fragile surface from mechanical damage. The membrane is particularly useful in the purfication of hydrogen.

Reactant materials for use in the synthesis of compounds comprising a non-metal and hydrogen, and methods of making and using the same are provided. The reactant materials generally comprise first and second non-metals, metals, a cation, and a transition metal, and can be formed and used in reactions occurring at relatively low-pressure conditions using heat energy that can be supplied via solar radiation. In particular, the reactant materials can be used in the synthesis of ammonia and various hydrocarbon compounds using air, water, and sunlight.
