Microporous, highly monodisperse single‐crystal‐like NaTi 2 (PO 4 ) 3 nanoparticles with a strong acidic surface and uniform size are prepared by using calf thymus DNA as a structure‐directing agent under acidic conditions. The nanoparticles (see image) were very active, stable, and selective catalysts for the ketalization of cyclohexanone and 1,2‐ethanediol to cyclohexanone ethylene ketal.
