Calcined UTL-type germanosilicate was firstly reduced in a hydrogen atmosphere at an appropriate temperature. Then, air-calcination and water-washing procedures were performed to remove the Ge metal clusters or crystals originated from the reduction of skeleton germanium(iv) to yield pure zeolite phase of two daughter structures analogous to IPC-2 and IPC-6.

Some catalytic reactions of cyclo pentanone vapour with hydrogen and with deuterium on evaporated metal films in a static system have been followed by means of a mass spectrometer. Hydrogenation to cyclo pentanol and hydrogenolysis with formation of cyclo pentane and cyclo pentene have been observed to different extents on films of rhodium, palladium, platinum, tungsten and nickel. Kinetic data, activation energies and frequency factors have been obtained for these reduction processes and possible mechanisms are discussed. Similar information has been obtained for the exchange reactions. An order of activity of the metals for inducing fission of the C—O bond is given. Preliminary experiments with cyclo hexanone have indicated an analogous behaviour to that found for cyclo pentanone. A comparison is drawn between the reactions of the cyclic ketones and those found for acetone (Stoddart & Kemball 1956; Kemball & Stoddart 1957).

An investigation has been made of the activation of copper by successive oxidation and reduction with hydrogen. Reduction with carbon monoxide causes deactivation of the surface. The heats of adsorption of carbon monoxide and oxygen and the heat liberated during the catalytic reaction of carbon monoxide and oxygen on a cuprous oxide film formed on metallic copper have been measured at room temperature. The kinetics of the reactions have been studied. The electrical conductivity of thin films of oxides has been measured during the reduction with hydrogen, and a study made of the process of embrittlement, whereby the surface is activated. The effect of the adsorption of gases on the conductivity of the Cu 2 O-CuO surface has been investigated. Oxygen enhances the conductivity and carbon monoxide and hydrogen depress it. The reaction between carbon monoxide and oxygen has been followed at room temperature by conductivity measurements and the results have been employed to interpret the nature of the adsorption, the kinetics of the reaction, and the deactivation of the surface by carbon monoxide.
