In the methane combustion catalyst, a ratio RTO of platinum oxides to metal platinum is 8.00 or more, wherein the ratio RTO is based on existence percentages of the metal platinum (Pt) and the platinum oxides (PtO and PtO2) obtained from a platinum 4f spectrum analyzed and measured by X-ray photoelectron spectroscopy (XPS) and calculated in accordance with the following expression. In the following expression, RPt is an existence percentage of the metal platinum (Pt), RPto is an existence percentage of PtO, and RPto2 is an existence percentage of PtO2.


RTO=(RPtO+RPtO2)/RPt  [Expression 1]

Abstract: The present invention discloses a mesoporous manganese ferrite Fenton-like catalyst and preparation method and application thereof and pertains to the field of preparation of Fenton-like catalysts. The present invention uses KIT-6 as a hard template agent to synthesize mesoporous manganese ferrite catalyst. The prepared mesoporous manganese ferrite and hydrogen peroxide constitute a Fenton-like system oxidation wastewater treatment system to carry out efficient removal and mineralization of organic pollutants in wastewater. The preparation method of the present invention is simple and efficient. The prepared Fenton-like catalyst has a mesoporous structure and a relatively large specific surface area. It can provide more adsorption sites and catalytic site and efficiently degrade pollutants in a wide pH range (acidic, neutral and even alkaline) and solves the problem that conventional Fenton reaction occurs only under an acidic condition and a large amount of iron sludge is generated during reaction, causing secondary pollution. Further, the catalyst can be used cyclically and easily separated from the water solution and recovered after use.
