Coating of BiFeO۳Nanostructure on the Glass Supports and Kinetic Study of Photocatalytic reduction of NOx

Abstract:In this study BiFeO۳ (BFO) nanocrystals were synthesized by sol-gel methodand were coated on the glass platesusingsuspension method withchemical pre-treatment and applied to removal of NOx pollutant. Results showed that withincreasing NOx concentration, photocatalytic conversion decrease. Kinetic studies showed that the reaction followsthe firstorder with a good approximation. Based on Langmuir- Hinshelwood (L-H) model the adsorption equilibrium constant (kads)and kinetic rate constant of surface reaction (kc) were obtained ۰.۰۵۸ mgl-۱min-۱, ۰.۰۴۹ l mg-۱ respectively. Finally the rateequation was proposed to estimate the residual NOx.
