Mesoporous phenolic resin/copper nano particle heterogeneous catalyst, and preparation method and application of catalyst

Abstract

The invention discloses a mesoporous phenolic resin / copper nano particle heterogeneous catalyst, and a preparation method and an application of catalyst. With ordered mesoporous phenolic resin as carrier and elementary substance state copper nano particle as catalyst active component, the heterogeneous catalyst has a regular mesoporous structure, as well as has the characteristics of large specific surface area, uniform particle size distribution, even active site distribution and the like; meanwhile, the catalyst has high chemical and thermal stabilities, can be dispersed well in a reaction system, is easy to recover and recycle, and is widely applied to each elementary copper based organic catalytic reaction. Furthermore, the preparation process of the catalyst is simple, the raw materials are cheap and available, the cost is low, and no reducing agent is added during the preparation process, so that the environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to a heterogeneous catalyst and a preparation method thereof, in particular to a novel mesoporous phenolic resin-loaded copper nanoparticle heterogeneous catalyst, a preparation method and application thereof. Background technique [0002] In recent years, mesoporous materials, such as mesoporous silica materials, mesoporous polymer materials, etc., have been widely used in catalysis, adsorption and drug release due to their advantages of specific surface area, large pores, adjustable pore size and rich and variable organic functional groups. has received extensive attention. At present, the preparation methods of mesoporous material-loaded metal nanoparticle catalysts include impregnation method, ion exchange method, vapor deposition method, etc. These methods are to prepare mesoporous materials first and then graft the metal nanoparticles. In the preparation process, generally It also needs to add a reducing agent such as sodiu...

Problems solved by technology

At present, the preparation methods of mesoporous material-loaded metal nanoparticle catalysts include impregnation method, ion exchange method, vapor deposition method, etc. These methods are to prepare mesoporous materials first and then graft the metal nanoparticles. In the preparation process, generally It also needs to add a reducing agent such as sodium borohydride or roast in a reducing atmosphere, so there are many shortcomings, such as uneven particle size distribution, mesoporous structure damage, cumbersome preparation process, high cost, time-consuming and labor-intensive, etc.

It is completely far from the concept of green atomic economics, economic benefits, and can not obtain satisfactory catalytic performance
