Abstract
The invention relates to a preparation method for a nitrogen-doped porous carbon-silicon composite material. According to the preparation method, an SBA-15 molecular sieve is used as a hard template, and urea is used as the raw material, ground fully and calcined for 2-5 hours at the temperature which is increased to 550 DEG C according to a program of (1-15) DEG C/min in a muffle furnace, and then the nitrogen-doped porous carbon-silicon composite material can be prepared. The system is a mild thermal polymerization reaction system and has a good application prospect in industrial production.
Description
Technical field
The invention belongs to inorganic composite materials field, relate to a kind of preparation method of N doping type porous carbon silicon composite.
Background technology
Carbonitride similar graphite flake layer stacked structure, has the good characteristics such as unreactiveness, thermostability, bio-compatible, optical characteristics, safety non-toxic, environmental protection.Broad prospect of application is had in fields such as catalysis, support of the catalyst, material, optics, electronics.Following carbonitride likely substitutes graphitic carbon material in various materials science applications, and such as, the alternative graphite carbon of carbonitride makes electrode materials.Traditionally, the specific surface area of graphite phase carbon nitride is not high enough, and its application is limited.Comparing, utilize mesoporous silicon based molecular sieve for hard mould agent, take urea as the raw material of preparation graphite phase carbon nitride, synthetic nitrogen doping type porous carbon silicon composite.This material specific surface area is high and have both the various characteristics of graphite phase carbon nitride, and it has potential using value and important application prospect.
