摘要： PURPOSE:To uniformly and strongly immobilize superfine particles of gold and to increase the catalytic activity by immobilizing the superfine particles of gold whose particle diameter has a specified value on metallic oxide incorporating titanium as the main component. CONSTITUTION:The superfine particles of gold whose particle diameter is 250 angstrom or below are immobilized on a metallic oxide incorporating titanium as the main component. In the method, pH of liquid containing metallic oxide incorporating titanium used for a carrier as the main component is firstly regulated to about 7-11. The aqueous solution of a gold compound is dropt into the aqueous solution thereof under agitation. Gold hydroxide is made to adhere to metallic oxide incorporating titanium as the main component. Then the superfine particles of gold are deposited and immobilized on the surface of titanium-based oxide by heating the titanium-based metallic oxide to which gold hydroxide is made to adhere at about 100-800 deg.C. As metallic oxide incorporating titanium as the main component, multiple oxide containing titanium such as FeTiO3 is used in addition to TiO2. Thereby an oxidation catalyst, a reduction catalyst and a catalyst for a combustible gas sensor and an electrode wherein catalytic activity is excellent are obtained easily and efficiently.

摘要： PURPOSE:To provide a cosmetic compounded with ultrafine gold particle-fixed metal oxide prepared by fixing the ultrafine gold particles to the metal oxide, having excellent light resistance and high stability and capable of controlling the color thereof in dependence an the preparation method. CONSTITUTION:A cosmetic is compounded with an ultrafine gold particle-fixed metal oxide prepared by uniformly and strongly fixing the ultrafine gold particles to the metal oxide (e.g., Al2O3, ZnO or TiO2) and has a new color tone and a new feeling of use. The gold-fixed metal oxide is prepared, for example, by dropping a gold compound aqueous solution in a metal oxide- containing aqueous solution having a pH of 7-11 while keeping the pH and subsequently heating the metal oxide at 100-1000 deg.C or by dropping a reducing agent in a metal oxide-containing aqueous solution containing the gold compound therein and having a pH of 7-11 to deposit the ultrafine gold particles on the metal oxide and, if necessary, heating the product at 100-1000 deg.C. The ultrafine gold particle-fixed metal oxide is especially compounded in an amount of 0.1-95wt.% for make-up cosmetics utilizing the characteristics of the color tone.

摘要： PURPOSE:To provide high sensitivity to CO2 even at about 100-300 deg.C working temp. and to detect even the trace CO2 of 100-500ppm with high sensitivity by using the detecting material consisting of tin oxide immobilized with superfine gold particles and Mg compd. CONSTITUTION:An aq. soln. contg. a water soluble tin compd. (for example, SnCl2, etc.) and water soluble gold compd. (AuCl4, etc.) is prepd. The prepd. aq. soln. and an aq. soln. of an alkaline compd. such as ammonium, etc., are stirred and mixed to adjust the pH of the aq. soln. to about 6-11. The mixture composed of the hydroxides of the silver and gold is obtd. as coprecipitate by this operation. The coprecipitate is washed and dried to form powder which is then impregnated with an aq. soln. of the water soluble compd. (hydroxide, nitrate, etc.) of Mg or M and is again dried to form powder. The resultant powder is heated to convert the tin compd. to an oxide and to decompose the gold hydroxide to obtain the superfine gold powder, by which the detecting material for the CO2 sensor is obtd. The high sensitivity to the CO2 is obtd. as shown in the figure at the working temp. of about 100-300 deg.C and even the trace CO2 is selectively detected if this material is used.
