Abstract:A facile method is reported to construct monolithic microreactor with high catalytic performance for Knoevenagel reaction. The microreactor is based on hierarchically porous silica (HPS) which has interconnected macro- and mesopores. Then the HPS is surface modified by pyrogallol (PG) polymer. Al(NO3)(3) and Mg(NO3)(2) are loaded on the surface of HPS through coordination with-OH groups of PG. After thermal treatment, Al(NO3)(3) and Mg(NO3)(2) are converted Al2O3 and MgO. The as-synthesized catalytic microreactor shows a high and stable performance in Knoevenagel reaction. The microreactor possess large surface area and interconnected pore structures which are beneficial for reactions. Moreover, this economic, facile and eco-friendly surface modification method can be used in loading more metal oxides for more reactions. (C) 2016 Elsevier Inc. All rights reserved.
