Abstract
In this investigation, removal of gaseous toluene was has been performed adopting FeWO4 /g-C3 N4 composites. The collected data and analyses have indicated that a combination of the two components (g-C3 N4 and FeWO4) in the mode of FeWO4 /g-C3 N4 composite showed better catalytic efficiency for gaseous toluene remediation compared to that of the individual constituents themselves. The performed enhancement has been done through the direct Z-scheme tool. In this system, as the result of the special amalgamation between g-C3 N4 and FeWO4, there was a combination of the photoexcited electrons from the conduction band (C.B.) of the FeWO4 with the photo-excited holes from the valence band (V.B.) of the g-C3 N4 whereas, the holes in the V.B. of the FeWO4 and the electrons in C.B. of the g-C3 N4 were preserved. And so, the powerful quantity of accessible holes and electrons could be produced via the synthesized FeWO4 /g-C3 N4 composite, which by their role, contributed strongly to the photo-catalytic destruction of the gaseous toluene although beneath visible light. The equal molar ratios of FeWO4 and g-C3 N4 (1Fe/1C material) have proven to possess the greatest photo-catalytic remediation of gaseous toluene. Gaseous toluene has been removed and mineralized adopting the synthesized 1Fe/1C material with percentages of 96.6% and 99.6%, respectively. In addition, the synthesized FeWO4 /g-C3 N4 composite showed great stability all over the removal process of toluene.
