Abstract

The invention discloses an ordered mesoporous carbon co-loaded cerium dioxide and binuclear cobalt phthalocyanine material and a preparation method thereof. The preparation method comprises the following steps: (1) adding an ordered mesoporous carbon material into de-ionized water, a cerium nitrate solution and a sodium hydroxide solution; mixing and stirring for 3 to 4h; filtering, washing and drying at 100 to 120 DEG C for 1 to 3h; roasting to obtain a cerium dioxide doped ordered mesoporous carbon material; (2) mixing the cerium dioxide doped ordered mesoporous carbon material, de-ionized water and binuclear cobalt phthalocyanine and carrying out ultrasonic treatment for 4 to 6h; drying at 60 to 80 DEG C for 10 to 15h to obtain the ordered mesoporous carbon co-loaded cerium dioxide andbinuclear cobalt phthalocyanine material. The preparation method disclosed by the invention is low in cost; adopted raw materials have no obvious toxicity on human bodies, and influences on a materialmesoporous structure in a synthesis process can be reduced to the greatest extent so that cerium dioxide can be doped into the ordered mesoporous carbon material.

Description

technical field [0001] The invention belongs to the field of mesoporous materials, and in particular relates to an ordered mesoporous carbon co-supported ceria and dinuclear cobalt phthalocyanine material and a preparation method thereof. Background technique [0002] There are 17 rare earth elements in the periodic table, including 15 elements of the lanthanide series plus the closely related elements scandium and yttrium. Cerium (Ce) is the most abundant rare earth element, and it is widely used in solid oxide fuel cells, catalysts, ceramics, and ultraviolet absorption. A prominent feature of cerium is that it can form CeO by releasing and capturing oxygen in an oxygen atmosphere. 2-x Oxide, so that the valence state of cerium element is in Ce 3+ and Ce 4+ Transformation between these compounds leads to the formation of vacancies on the surface of the compound, called "oxygen-deficient sites". It is because of these defect sites that ceria (CeO 2 ) materials have exce...
