“…As shown in Fig.4, the FTIR spectra of pure FeVO 4 and Pt/FeVO 4 composite show that Pt/FeVO 4 has C = H stretching at peak 1731 cm − 1 as well as C-O and CO-H stretching at peaks 1032, 1052, and 1335 cm − 1 . VO 4 is responsible for the absorption peaks at low frequencies of 730 cm − 1[13,[24][25][26][27].…”

We prepared a unique platinum doped iron vanadate (Pt/FeVO4) composite for escalating the photocatalytic performance via the facile hydrothermal method using iron nitrate (Fe(NO3)3.9H2O), Ammonia metavanadate (NH4VO3) and chloroplatinic acid (H2PtCl6), as major precursors. Characterization results revealed that the FeVO4 and well dispersed platinum Pt/FeVO4 are in the range of around 150 nm to 200 nm size, which developed transportations of the photo-generated electron into FeVO4, consequently efficient separation of the photo-generated carrier in coupled Pt/FeVO4 nanocomposites heterostructure. The multi characterizations result indicated that excellent adsorption abilities of Pt/FeVO4 composites were strongly associated with Pt doping. The induce impedance spectroscopy and Photoluminance results demonstrated that Pt enhances separations efficiency as well as transferring rates for photo-generated charge. The EPR data suggest that reactive oxygen species (OH•, h+, •O2) were the most important factors in methylene blue (MB) degradation. As a result, Pt/FeVO4 exhibits the greater photocatalytic ability to degradations for MB dye for visible light irradiation compared to pure FeVO4.
