Abstract

Background and Objective: FORMALDEHYDE is a toxic volatile organic compound, which its removal from polluted air is essential. One of the techniques available for removing such compounds is photo catalytic degradation. The aim of this study was to investigate the photo catalytic degradation of gaseous FORMALDEHYDE on TiO2 nanoparticles coated on reduced graphene oxide.Materials and Methods: The synthesized reduced graphene oxide- TiO2 nano composite was characterized using SEM, EDS, and FTIR spectra. The photo catalytic activity of prepared reduced graphene oxide- TiO2 nano composite was investigated for degradation of gaseous toluene under different operational conditions such as different initial concentration, flow rate, and time.Results: The photo catalytic degradation efficiency of the RGO-TiO2 nano composite was much higher than P25 TiO2. The photo catalytic degradation efficiency of the RGO-TiO2 nano composite decreased by increasing the flow rate so the flow rate is a key factor for the use of RGO-TiO2 nano composite as a photo catalyst. The results showed that the photo catalytic degradation rates decreased from 89 to 30% with increasing FORMALDEHYDE initial concentration from 0.1 to 1 ppm.Conclusion: This research indicated that RGO-TiO2 nano composite can be effectively used as suitable photo catalyst to remove gaseous pollutants. One of the advantages of the as-prepared composite was using visible light instead of UV to activate the oxidation process.
