Rational design of bifunctional zeolites by SAC and their catalytic application |
| 초록 |
A highly crystalline pomegranate-like base-acid bifunctional beta zeolite was successfully synthesized by the steam assisted crystallization method using a basic nitrided N-beta as a starting material. The secondary crystal growth of a beta zeolite generating acid functionality occurred over the outer surface and intercrystalline void spaces of the N-bata zeolite. The pomegranate-like N-beta@H-beta zeolite had a high surface area and base-acid dual functionality, due to the well-connected framework topologies of the H-beta and N-beta crystallites. The N-beta@H-beta zeolite exhibited a superior yield of benzylidenemalononitrile during the tandem deacetalization-Knoevenagel condensation of benzaldehyde dimethyl acetal and malononitrile compared to H-beta, N-beta, and their physical mixture. This is likely due to the isolated and balanced activity of the base and acid catalyzed reactions. |
