Embodiment 1

[0014] Embodiment 1 utilizes oxidation method to prepare graphene oxide.

[0015] Combining graphene oxide and mesoporous silicon to construct a two-dimensional layered graphene-mesoporous silicon precursor.

[0016] 0.5 g of cerium nitrate was dissolved in 3 mL of ethanol solution, and then mixed with 0.2 g of graphene-mesoporous silicon composite, and dried and calcined to prepare cerium oxide and graphene-mesoporous silicon composite.

[0017] The prepared cerium oxide, graphene-mesoporous silicon composite material and strong alkali solution are mixed and heated, and after a series of basic treatment processes such as washing, filtering and drying, a graphene-supported two-dimensional ordered layered Ceria support.

[0018] Mix 0.2 g of graphene-supported two-dimensional ordered layered ceria carrier with 1.2 mL of 1 g / 100 mL chloroauric acid and 2.25 mL of 1 g / 100 mL polyvinyl alcohol, and finally add 4.5 mL of 0.38 g / 100 mL sodium borohydride and stirred for 90 minute...

Description

technical field [0001] The invention relates to a preparation method of a two-dimensional layered glycerol oxidation nano catalyst. Background technique [0002] The contradiction between energy crisis and economic development is becoming more and more prominent. At present, biomass diesel is an ideal substitute for fossil fuels. Biodiesel has a wide range of sources, high combustion calorific value, low environmental pollution and large-scale production, so it has a wide range of applications. Prospects and economic markets. However, in the production process of biodiesel, a large amount of glycerol by-products will inevitably be generated. The accumulation of by-products will not only cause energy waste, but also limit the promotion and use of biodiesel. Glycerol is an important basic raw material in the chemical industry. Products with higher economic benefits can be obtained through a series of different catalytic reactions. Among them, the selective oxidation of glycer...
