Embodiment Construction

[0041] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are specifically cited below, together with the accompanying drawings, as follows:

[0042] The invention prepares and forms an iron complex, and the iron complex can be further applied to the preparation method of iron oxide or iron oxide / carrier catalyst.

[0043] 1. the preparation method of iron complex of the present invention:

[0044] The preparation method of the iron complex of the present invention comprises a chelating step. This chelation step will ferric chloride (ferric chloride, FeCl 3 ) and at least one chelating agent (chelating agent) are placed in a solvent and mixed to form an iron complex solution, so that the iron ion Fe dissociated from ferric chloride in the solvent 3+ React with the at least one chelating agent, so that iron ions are coated in the chelating agent to for...

Abstract

The invention relates to a preparation method of an iron complex, which is implemented by mixing iron chloride and at least one chelator in a solvent, so that iron ions Fe<3+> of the iron chloride react with the at least one chelator to form the iron complex of which the general formula is Fe[R1]a[R2]b[H2O]c<3+> or Fe[R1]a[H2O]c<3+>, wherein R1 and R2 are respectively one of diethylenetriamine, triethylenetetramine, ethylene diamine, 1,10-orthophenanthroline and 2,2'-dipyridine. The invention also provides a preparation method of iron oxide, which comprises the following steps: separating the iron complex from an iron complex solution, drying the iron complex, and carrying out heat treatment. The invention also provides a preparation method of an iron oxide / carrier catalyst, which comprises the following steps: mixing iron chloride, at least one chelator and a carrier in a solvent, and reacting to form an iron complex; drying the iron complex adsorbed to the carrier; and carrying out heat treatment on the dried iron complex adsorbed to the carrier, thereby obtaining the iron oxide / carrier catalyst.

Description

technical field [0001] The present invention relates to a complex and its application, in particular to an iron complex, a method for preparing the iron complex, a method for preparing iron oxide using the iron complex, and using the iron complex Preparation method for making iron oxide / carrier catalyst. Background technique [0002] At present, in the petrochemical and energy industries, the precious metal platinum is mainly used as a catalyst to promote redox reactions. In the petrochemical industry, platinum catalysts can help increase oil production. In addition, the exhaust gas purifiers equipped with most cars are catalyzed by platinum catalysts to convert carbon monoxide and unburned hydrocarbons into harmless carbon dioxide and water vapor. In the energy industry, the development of fuel cells for commercial use has received widespread attention, because fuel cells have the advantages of high efficiency and low emissions, and only emit harmless carbon dioxide, wate...
