Abstract
The invention discloses a dinuclear rhodium complex-doped platinum/hollow mesoporous silica sphere composite material, and a preparation method and an application thereof. The preparation method comprises the following steps: preparing hollow mesoporous silica by a selective etching technology, uniformly distributed a precious metal platinum in the channels of the hollow mesoporous silica by using simple impregnation, and mixing the obtained catalyst with dinuclear rhodium complex adsorbed silica gel to obtain the composite material integrating a chromogenic probe with the catalyst. The preparation method is simple, and the chromogenic performance of the dinuclear rhodium complex material and catalysis performance of the catalyst can achieve simultaneous detection and catalyst of CO; and the dinuclear rhodium complex has obvious response to CO, and has chromogenic change in the presence of 50 ppm CO, and the product prepared through the preparation method has excellent CO detection and treatment properties, and highly facilitates industrial application.
