摘要： Disclosed is a method for preparing a platinum-manganese dioxide/carbon complex for a positive-electrode material of a lithium-air battery. More specifically, a manganese dioxide/carbon complex is prepared by dispersing carbon in a manganese dioxide precursor solution and applying microwaves, filtering and drying to the resulting solution. Next a platinum-manganese dioxide/carbon complex is prepared by dispersing the manganese dioxide/carbon complex in ethylene glycol, adding a platinum precursor and applying microwaves to the resulting solution. The platinum-manganese dioxide/carbon complex synthesized according to the present invention exhibits lower overvoltage and higher current density in oxygen reduction and oxidation reactions as compared to either a manganese dioxide/carbon complex or a platinum/carbon complex.

摘要： Disclosed is a method for selective dealkylation of alkyl-substituted C9+ aromatic compounds using a bimodal porous dealkylation catalyst at a low temperature. The catalyst has a bimodal porous structure including both mesopores and micropores. The catalyst includes a crystalline aluminosilicate and a metal. The catalyst is highly active at a low temperature. According to the method, C9+ aromatic compounds substituted with at least one C2+ alkyl group as by-products formed by xylene production can be selectively dealkylated and converted to BTX, etc. on a large scale within a short time. In addition, the method is an environmentally friendly process entailing reduced waste treatment cost when compared to conventional mesitylene production methods. Therefore, high value-added mesitylene can be separated from low value-added C9+ aromatic compounds at lower cost compared to conventional methods. Furthermore, the supported metal catalyst is easy to recover after dealkylation and is recyclable, thereby contributing to reduced cost.

摘要： Disclosed is a method for preparing an MnO2/carbon composite for a lithium-air secondary battery by preparing a precursor solution by dissolving permanganate powder in distilled water, preparing a MnO2/carbon composite by dispersing carbon in the precursor solution and using a reducing agent, and mixing the MnO2/carbon composite with polyvinylidene fluoride (PVdF) and supporting the mixture on nickel foam. According to the method for preparing a MnO2/carbon composite for a lithium-air secondary battery, the MnO2/carbon composite is prepared by dispersing carbon in a permanganate solution, instead of simply mixing carbon with manganese oxide, and thus the binding force between carbon and manganese oxide and the dispersion of carbon in manganese oxide can increase. The MnO2/carbon composite prepared by the above method has improved catalytic performance as an air electrode for a lithium-air secondary battery and thus can be effectively used as an electrode material for lithium-air secondary batteries.
