Photo-synergistic promoted in situ generation of Bi0–BiSbO4 nanostructures as an efficient catalyst for nitrobenzene reduction

摘要: This work reports on the synthesis of BiSbO4 micro-flowers by a facile hydrothermal method. All as-prepared samples were carefully characterized X-ray diffraction, scanning electron microscopy, transmission microscopy and photoelectron spectroscopy. TEM XPS results indicated that partial Bi3+ ions in nanoparticles situ converted into metallic bismuth to form Bi0–BiSbO4 nanostructures presence NaBH4 during reduction 4-nitrophenol. The was found be an efficient, renewable green noble metal free catalyst toward catalytic nitrobenzenes. Moreover, UV light can promote bismuth, which robustly photo-synergistically accelerate apparent reaction rate for nitrobenzenes aminobenzenes. generation may provide new possibilities development novel bismuth-based systems applications.
