Highly Ordered Mesoporous Carbon Nitride Nanoparticles with High Nitrogen Content: A Metal-Free Basic Catalyst

摘要

Mesoporous silica nanoparticles (MSNs) with controlled size, morphology, and tunable porosity have been receiving much attention due to their applications in the fields of drug delivery, catalysis, adsorption, separation, and fuel cells. Various MSNs with different functional groups and structures have been prepared and utilized for drug and gene delivery, while mesoporous nanoparticles composed of carbon and nitrogen are of particular interest for basic catalysis and the capture of carbon dioxide. Carbon nitride (CN) is a well known and fascinating material that has attracted worldwide attention because the incorporation of nitrogen atoms in the carbon nanostructure can enhance the mechanical, conducting, field-emission, and energy-storage properties.
