N2 - Metal oxide nanocomposite has become more attention research considered as multifunctional materials. The development of synthesis method of nanocomposite is an essential aspect primarily to obtain eco-friendly and easy preparation materials. Herein, we present for the first time a facile approach for the preparation of V2O5-Fe2O3 nanocomposites by a one-pot sol–gel via Foeniculum vulgare extracts and their catalytic property in the reduction of 4-nitrophenol to 4-aminophenol with a reducing agent of NaBH4. The FT-IR result revealed that the secondary metabolites content in Foeniculum vulgare extracts plays a significant role as capping and hydrolyzing agents. The TEM image showed that the particle size of V2O5-Fe2O3 nanocomposites was 90 nm. Moreover, the reduction of 4-nitrophenol over V2O5, Fe2O3, and V2O5-Fe2O3 were investigated. Among them, V2O5-Fe2O3 nanocomposites exhibited the highest catalytic property for reduction of 4-nitrophenol. The significant improvement of catalytic property was observed by the presence of Fe2O3, which has a significant role in facilitating a rapid electron transfer between 4-nitrophenol and NaBH4. Moreover, the increase of catalytic property over 94% to reduce 4-nitrophenol to 4-aminophenol could be attributed to the synergistic effects between V2O5 and Fe2O3 in the V2O5-Fe2O3 nanocomposites as an efficient reduction catalyst.
