Study on the structural and photocatalytic properties for pore size tailored SnO2-pillared layered titanate nanohybrids.

A new mesoporous SnO2-pillared layered titanate is prepared by hybridizing the exfoliated titanate nanosheets with SnO2 nanosol particles. The pore size tailored porous nanohybrids (SBET = 74 approximately 280 m2/g and d = 18 approximately 96 angstroms) are obtained after calcining an as-prepared sample. The mesoporous nanohybrids exhibited different photocatalytic behaviors for salicylic acid and methylene blue depending upon their crystallinity and porous structure.
