Abstract

A method for easily preparing an array of vertical graphene nanosheets, comprising the following steps, step 1: coating a suitable carbon-containing solid-phase precursor solution, powder, colloid, etc. on a catalytic substrate and Drying; Step 2: Put the carbon-containing precursor in a tube furnace, and under the protection of an inert gas, increase the temperature in the furnace to realize the preparation of the vertical graphene nanosheet array. The invention has the following advantages: first, the equipment is simple and easy to operate and maintain, and can be produced on a large scale; second, the preparation process is simple, low labor intensity, low energy consumption, does not involve high temperature and high pressure, and satisfies the concept of safe and green production ; Third, the grown upright graphene nanosheets can be a single layer or a few layers (≤10 layers).

Description

technical field [0001] The invention relates to a method for manufacturing vertical graphene nanosheets, in particular to a large-scale preparation method for an array of vertical graphene nanosheets (Vertical Graphene Nanosheets). Background technique [0002] Vertical Graphene Nanosheets, also known as carbon nanowalls, are two-dimensional nanostructures with open edges. This unique carbon nanostructure makes it widely used in chemistry, biosensing, energy storage, etc. [0003] At present, the production methods of vertical graphene nanosheets mainly include plasma enhanced chemical vapor deposition (PlasmaEnhanced Chemical Vapor Deposition, PECVD), hot filament chemical vapor deposition (Hot FilamentChemical Vapor Deposition, HFCVD), and the latest thermal chemical vapor deposition (Thermal Chemical Vapor Deposition). Chemical Vapor Deposition, TCVD). However, these methods are complex in operation and expensive in equipment, and it is not easy to realize the industria...
