HOTOCATALYTIC REDUCTION OF Cr (VI) by PMo12/TiO2 ELECTROSPUN NANOFIBER COMPOSITES
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
Polyoxometalates (H3PMo12O40, abbr. PMo12)/TiO2 nanofiber composites were fabricated by a facile electrospinning/calcination method. In the structure, PMo12, as an electron relay, can accept the photo-generated electron from the conduction band of TiO2, which promotes the charge separation. Then the electron stored on PMo12 further transfers to the Cr (VI) in the solution to realize the removal of Cr (VI). The PMo12/TiO2 nanofiber composites exhibit enhanced photocatalytic performance for photocatalytic reduction Cr (VI), which are expected to be one kind of new and environmentally friendly catalyst for removal of inorganic pollutants in water.
