AI Technical Summary
Existing methods for preparing carbon-coated silicon nanomaterials have problems such as safety hazards, high cost, cumbersome operation, and difficulty in large-scale production.
A microwave plasma treatment method was adopted to prepare carbon-coated silicon nanomaterials by mixing carbon and silicon sources and then subjecting the mixture to microwave plasma treatment. This method avoids flammable and explosive gas sources, simplifies the operation, and allows the process to be carried out under normal pressure.
A safe, convenient, and simple method for preparing carbon-coated silicon nanomaterials has been achieved. The nanomaterials have small and uniform particle sizes, avoiding oxidized functional groups and metal impurities, making them suitable for industrial production.
