Problems solved by technology

The van der Waals force and π-π stacking between graphene sheets make graphene sheets tend to recombine and aggregate, which becomes an important factor restricting the practical application of graphene. Building it into a three-dimensional structure (3D-rGO) can be very good to solve th...

Abstract

The invention relates to a composite catalytic material of MIL-101 (Fe) in-situ formed on 3D-rGO, and a preparation method and application thereof. According to the composite catalytic material, 3D-rGO is used as a carrier; an in-situ synthesis method is used for in-situ synthesis of MIL-101 (Fe) or MIL-101(Fe)-NH2 in graphene; then heat treatment is carried out in a vacuum environment to remove molecular water on Fe molecules and to expose acidic sites on the Fe molecules; and thus, the material is improved in stability and catalytic performance. The composite catalytic material can efficiently degrade cellulose into small-molecular acid, and realizes the recycling of the waste. Compared with traditional catalytic materials for cellulose catalysis, the composite catalytic material of theinvention has higher selectivity, milder catalytic conditions, better catalytic efficiency and fewer by-products, and thus has broad application prospects in actual production.

Description

technical field [0001] The invention relates to a MIL-101(Fe) composite catalytic material generated in situ on 3D-rGO and its preparation method and application, belonging to the field of chemistry and environment technology. Background technique [0002] With growing concerns over energy shortages and environmental degradation, the search for renewable and green energy sources as an alternative to petroleum production has attracted worldwide attention. In recent years, the conversion of biomass into chemicals or liquid fuels has attracted great interest, among which the degradation of cellulose into high value-added platform compounds is considered to be one of the most important directions. As a large agricultural country, my country produces more than 72 million tons of straw every year, most of which are used as fuel for direct combustion, which will not only cause environmental pollution, but also cause waste of resources. [0003] Straw contains 40-60% natural cellul...
