Iron oxide nanorod catalyzed oxidation of styrene by H₂O₂.

Entry	R	Time (h)	Yield (%)^a	Selectivity (%)^b
1	H	12	72	98
2	4-Me	12	80 (70)^c	99 (97)^c
3	4-OMe	12	80	99
5	4-NO2	12	75	98

aYield refer to those of pure products characterized by ¹H NMR and IR spectroscopic data. ^bSelectivity based on olefine conversion. ^cThe results in the bracket are obtained after 4th cycle.
