A facile template carbonization strategy has been used for the synthesis of ordered mesoporous silica microspheres with sulfonated carbon nanoparticles trapped inside by combining solvent‐evaporation‐induced aggregating assembly, in situ carbonization, and sulfonation treatments. The obtained SO 3 H‐bearing microspheres show an excellent catalytic performance in the condensation reaction of benzaldehyde with ethylene glycol.
