“…Though the catalytic hydration of epoxides has aroused extensive research attention, it still lacks of efficient solid catalysts being able to catalyze the hydration reaction with high glycol selectivity at H 2 O/epoxide ratio less than 5. [2][3][4][5][6][7] Previous studies showed that the silica-based nanoreactor with encapsulated Co (Salen) could catalyze the hydration of epoxides at H 2 O/epoxide ratio around 2 to afford much higher activity and high selectivity than homogeneous counterpart. [8][9] DFT studies suggested that Co(Salen) goes through bi-molecular activation pathway for the hydration of epoxides.…”

Microporous polymers have been considered as promising heterogeneous catalysts for versatile chemical transformations. However, the mass diffusion barriers through the microporous network still remains a big hindrance. Herein, an efficient and versatile strategy for shortening the mass diffusion pathway through microporous polymer was reported by constructing a CNTs@POP‐salen core‐shell nanostructure. CNTs@POP‐Co(salen) could efficiently catalyze the epoxide hydration reaction at H2O/epoxides ratio as low as 2, demonstrating the efficient cooperation of Co(salen) integrated in the polymer network. CNTs@POP‐Co(salen) showed much higher activity than bulk polymer in propylene oxide (PO) hydration reaction (TOF: 3150 versus 1470 h−1) due to the shortened diffusion pathway, which was further confirmed by adsorption experiment using phenol as probe molecule. Our primary results demonstrated the advantages of core‐shell nanostructures to improve the catalytic activity of microporous polymers by enhancing the mass diffusion during the catalytic process.
