Patent ID: 11996549

Abstract:
A method for preparing a silicon monoxide composite material includes: a first stage: introducing a protective gas into a vapor deposition oven, and pre-heating a silicon monoxide raw material, such that a part of the silicon monoxide raw material is subjected to a disproportionation reaction; a second stage: continuously introducing the protective gas and introducing a carbon source gas, and subjecting the pre-heated silicon monoxide raw material to a chemical vapor deposition to form carbon nanotubes on a surface of silicon monoxide; and a third stage: after a predetermined time period, stopping introducing the carbon source gas, and stopping introducing the protective gas until the vapor deposition oven is cooled to room temperature, to prepare the silicon monoxide composite material. During the preparation process, no extra catalyst needs to be added, a product of the previous disproportionation reaction may act as a catalyst for the growth of the carbon nanotubes.
