Abstract

Gallic acid and urea are used to produce C2NO materials with rather dined micropores via direct condensation and ring closure. The materials show a unique heterocycle containing carbonaceous structure and features an unusually high content of heteroatoms (nitrogen, oxygen) lining inside the pores, meanwhile having high specific surface area. The multifunctional carbon materials demonstrate good performance for selective CO2 capture resulting from the adjustable porosity and polarizability. In view of the simplicity of the salt flux synthetic method and the advantage of the available sustainable starting synthons, the C2NO framework has potential for use in diverse practical applications.
