Summary, etc. |
The nanoparticles of WO<sub>3 </sub>doped with Fe ions have been employed for University, Kermanshah photocatalytic conversion of greenhouse gaseous of CO<sub>2</sub> and CH<sub>4</sub> under visible-light irradiation. The photocatalysts have been characterized by XRD, FESEM, EDX, Raman, UV-vis, and PL techniques. The XRD and Raman spectroscopies confirm the monoclinic structure of WO<sub>3</sub> nanoparticles and also the successful incorporation of Fe ions into WO<sub>3</sub> lattice. A red shift in Raman patterns of Fe-doped WO<sub>3</sub> samples indicate the partial substitution of W with Fe ions and the structural defects induced in WO<sub>3</sub> crystals upon doping treatment. The recorded PL signals reveal that the charge carrier recombination rate can be inhibited by doping WO<sub>3</sub> with Fe ions. The modified samples show high activity by photons with wavelength equal to/greater than ~500 nm, the visible-light in green region. The best photocatalytic reduction of CO<sub>2</sub> is provided to be 38.7% by WO<sub>3</sub> containing 4.18 at.% Fe under visible-light. Ethane, and formate and acetate derivatives are detected as the major products of CO<sub>2</sub> reduction. |
