Abstract This study proposes a simple approach for the fabrication of microspherical catalysts with a
hierarchical porous structure. The cross-linked porous microspheres with catalytic ability were
prepared directly from small-molecular monomers via low-temperature phase-separation
photopolymerization of water/oil suspension. The morphology, pore size, chemical structure,
and thermal stability of the obtained porous microspheres were characterized by SEM, Mercury
Intrusion Porosimetry, FTIR, and TGA. The porous microspheres directly served as an acid
catalyst for the condensation reaction of benzaldehyde and ethylene glycol, which exhibited
superior catalytic activity and recyclability. The results indicated that such porous microspheres
have great More >
