An apparatus of adding high vapor pressure magnesium to a steel liquid, includes a magnesium additive device and a tube furnace. The magnesium additive device includes a storage barrel, a conveying pipe, a control valve, and an insertion tube. A method of adding high vapor pressure magnesium to a steel liquid, includes placing the magnesium additive device in the tube furnace, and delivering pure magnesium particles into the storage barrel. When the temperature at the mediate lower position of the conveying pipe is increased to reach a preset value, the control valve is opened to pour the pure magnesium particles into the conveying pipe to form a magnesium vapor, and an argon regulating valve is opened to introduce the argon into the conveying pipe so as to add the magnesium vapor to a steel liquid by carrying of the argon.

A manufacturing method of a platinum complex is mixing chloroplatinic acid and a chelating agent with a solvent, wherein [PtCl]ions of the chloroplatinic acid is reacted with the chelating agent to form a platinum complex Pt[R], wherein the chelating agent(R) is selected from ethylenediamine, 1,10-phenanthroline, 2,2'-Bipyridine, diethylenetriamine, triethylenetetraamine, phenanthroline, or bipyridine. Moreover, a method for producing a platinum catalyst on supports is mixing the chloroplatinic acid, a chelating agent and supports with a solvent to form a platinum complex, which is incorporated onto the supports. Following, a reduction step and a drying step are processed to get the platinum catalyst on the supports.

A manufacturing method of an iron complex is mixing ferric chloride and at least one chelating agent with a solvent, wherein Feions of ferric chloride is reacted with the at least one chelating agent to form an iron complex Fe[R][R][HO]or Fe[R][HO], wherein the at least one chelating agent is selected from a group including ethylenediamine, 1,10-phenanthroline, 2,2'-Bipyridine, diethylenetriamine, triethylenetetraamine, phenanthroline, or bipyridine. Moreover, a method for producing an iron oxide catalyst is mixing ferric chloride, at least one chelating agent and the support with a solvent to form an iron complex, which is incorporated with the support. Following, a drying step and a heat treatment step are processed to get the iron oxide catalyst.
