Abstract: A press switch shower faucet, that includes: a main body, on which is disposed a hot water inlet hole and a cold water inlet hole; and a valve cartridge, disposed inside the main body, on the valve cartridge is disposed a rotation switch for adjusting temperature, and a press switch for controlling open/close of a water channel. Through the design of the press switch shower faucet, the water temperature adjusting function and the water open/close function can be carried out independently, so that in the next time the user utilizes water, he may use the water directly without the need of adjusting water temperature, in achieving great convenience and satisfaction for the user.

Abstract: The inventive catalyst composition is a sponge metal catalyst comprising at least one skeletal porous sponge metal selected from the group consisting of nickel, cobalt, iron and copper, together with a first promoter metal selected from the group consisting of palladium, platinum, ruthenium, rhodium, osmium and iridium and a second promoter metal selected from the group consisting of iron, nickel, cobalt, zinc, vanadium, cerium, copper, tungsten, molybdenum, titanium, niobium, manganese, silver, cadmium, praseodymium and neodymium. Processes for the manufacture of the catalyst include impregnation or precipitation of the promoter metals onto the sponge metal catalyst.
