Abstract: To provide a reactor to improve evenness in the thickness of shell metals coated on the surface of core particles by increasing area sizes in the reactor chamber to control electric potentials, the present invention is configured to comprise a top surface able to move up and down while serving as a working electrode, a wall serving as a working electrode, a bottom surface, a standard electrode, a power supplying part and a solution injecting part, wherein the top surface can move up and down automatically by an electric motor or manually. Also, the top surface is configured to be suitable for the interior diameter of the reactor chamber, for solutions inside the reactor chamber not to leak from the top surface or from the crevice between the top surface and the wall of the reactor chamber. The bottom surface of the reactor chamber may comprise an impeller or an ultrasonic wave diffuser to bring about even diffusion in the reactor chamber.

Abstract: A photocatalyst laminate which is composed of an undercoat layer provided on a substrate and a photocatalyst layer laminated on the surface of the undercoat layer. The undercoat layer contains (A) 100 parts by mass of a resin component and (B) 0.1-50 parts by mass of fine core-shell particles, each of which has a core that is formed of a fine tetragonal titanium oxide solid solution particle wherein tin and manganese are solid-solved and a shell that is formed from silicon oxide on the outside of the core. This photocatalyst laminate is not susceptible to decrease in the photocatalyst function even under outdoor exposure for a long period of time, and is thus capable of providing a coated article that exhibits excellent weather resistance.

Abstract: The invention relates to a catalyst molded body, which is produced by deforming a mixture of a metal oxide and a special graphite. The invention further relates to a method for producing the corresponding catalyst molded bodies and to the use of the catalyst molded bodies for catalytic reactions in which hydrogen acts as a reaction reactant or reaction product, in particular hydrogenation, hydrogenolysis, and dehydrogenation reactions. The catalysts are characterized by an improvement in the activity and selectivity in particular in hydrogenation, hydrogenolysis, and dehydrogenation reactions, said improvement being achieved by adding special graphites.

Abstract: A system for use in selective catalytic reduction reactor is disclosed. The system may include a catalyst bed and a screen located close to the catalyst bed in a manner so that flow of flue gas to the catalyst bed contacts the screen before it contacts the catalyst bed. The screen may be adapted to support a weight of at least 400 pounds above the catalyst bed so that the weight is not imposed on the catalyst. The screen may have a plurality of holes across its surface in a manner so that the screen is adapted to change the velocity distribution of the flue gas as it flows through the screen.

Abstract: A method for stabilizing a metal or metal-containing particle supported on a surface is described, along with the resulting composition of matter. The method includes the steps of depositing upon the surface a protective thin film of a material of sufficient thickness to overcoat the metal or metal-containing particle and the surface, thereby yielding an armored surface; and then calcining the armored surface for a time and at a temperature sufficient to form channels in the protective thin film, wherein the channels so formed expose a portion of the metal- or metal-containing particle to the surrounding environment. Also described is a method of performing a heterogeneous catalytic reaction using the stabilized, supported catalyst.
