Abstract

The invention relates to a nano palladium immobilized filter paper and its preparation and application. The filter paper is formed by reducing PdCl42-adsorbed on the surface of the filter paper into palladium nanoparticles in situ to form the nano palladium immobilized filter paper. The filter paper is soaked in polyethyleneimine solution, washed with water, then soaked in potassium tetrachloropalladate solution, washed with water to obtain PEI / PdCl42-solid-loaded filter paper; the above-mentioned PEI / PdCl42-solid-loaded filter paper is soaked in sodium borohydride aqueous solution After soaking, take out the filter paper, wash with water, and dry in vacuum. Application of nanometer palladium immobilized filter paper as catalyst. The preparation process of the invention is simple, the preparation time is less, and it is very suitable for industrial production. The prepared nano palladium immobilized filter paper has the characteristics of high catalytic efficiency and good reusability. Therefore, it has broad application prospects in the fields of catalysis and environmental restoration.

Description

technical field

[0001] The invention belongs to the field of filter paper and its preparation and application, in particular to a nanometer palladium immobilized filter paper and its preparation and application. Background technique

[0002] Metal nanomaterials have become a research hotspot because of their many unique properties. In recent years, there have been many research reports on metal nanomaterials in the fields of sensors, drugs, medical imaging, catalysis and environmental governance, and research results on their applications in the field of catalysis. particularly prominent. For example, Claver et al. introduced in detail the research of palladium nanoparticles on the catalysis of C-C crosslinking reaction in organic reactions (Claver et al. Chem. Soc. Rev. 2011, 40, 4973-4985), but there is no carrier-immobilized palladium nanoparticles It is not easy to recycle and reuse, and its application potential will be greatly limited. Fixing or assembling nano-palla...
