      abstract = {Thin films of ferric oxide (?-Fe2O3) were synthesized starting from iron acetate nanopowder using the doctor blade method. Iron acetate powder was heated to 600 0C to crystallize the phase of ferric oxide.Then ferric oxide powder was mixed with PEG binder to make the thin film mechanically stable.Structural properties, grain size, strain and dislocation density of films were determined using the XRD patterns. Films with single phase of ferric oxide could be crystallized in thin film form according to XRD patterns. Chemical bonds in the thin films were investigated using FTIR spectrums. Optical band gap was measured using UV-Visible spectrums. Gas sensitivity was measured in 1000ppm of CO2 gas by measuring the electric current using AUTOLAB.The optimum gas sensitivity could be obtained by adding 2% of activated carbon powder to ?-Fe2O3 in mass ratio. Activated carbon added ?-Fe2O3 thin film showed 50.2% sensitivity in 1000ppm CO2 gas.},
