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

Abstract

Nitrogen-rich carbon nitride is obtained as ultrasmall, discrete, mesoporous nanoparticles (see picture) by reaction of ethylenediamine with CCl4 in the nanochannels of a mesoporous silica template. Its high nitrogen content, large surface area, and large pore volume make it a highly active catalyst for transesterification of β-keto esters of aryl, aliphatic, and cyclic primary alcohols.
