Egg Yolk Biomass Derived N‐Doped Ordered Mesoporous Carbon: Highly Robust Heterogeneous Organocatalyst for One‐Pot Deacatalization‐Knoevenagel Reaction

Abstract A novel and facile synthetic route for CMK‐3 type N‐rich ordered mesoporous carbon from cheap egg yolk biomass as a carbon precursor (EYCP) and SBA‐15 as a hard structure directing agent has been developed. To obtain a well‐ordered material, carbonization temperature was investigated. The N 2 adsorption‐desorption analysis proved that the synthetic mesoporous carbon material at 500 °C is highly ordered, with high surface area of 226 m 2 g −1 , and nitrogen content of 6.2% was determined by CHN analysis. Corresponding mesoporous materials were examined as bifunctional acid‐base organocatalysts in a one‐pot tandem deacetalization‐Knoevenagel reaction. Results showed that the modified carbon material which was synthesized at 500 °C exhabited high nitrogen content and reactivity in one‐pot deacetalization‐Knoevenagel reaction. Carboxylic acid and pyridinic nitrogen groups of carbon material play as a bifunctional acid and base catalyst.
