A　nano-structured　TiO2　thin　film　immobilized　on　glass　springs　was　prepared　by　the　sol-gel　method,　and　characterized　by　scanning　electron　microscopy　(SEM)　and　X-ray　diffraction　(XRD).　Acetone,　toluene　and　p-xylene　were　chosen　as　common　VOCs　for　a　photocatalytic　degradation　study　of　both　mixed　and　pure　gases　using　the　TiO2　thin　film.　Addition　of　hydrogen　peroxide　promoted　activation　of　the　catalyst　during　acetone　degradation.　The　effects　of　gas　flow　rate　and　UV　light　wavelength　were　investigated　with　the　pure　gases.　Gas　flow　rate　greatly　influenced　the　degradation.　The　highest　degradation　rates　were　77.7%　(at　3　L/min)　for　acetone,　61.9%　(at　3　L/min)　for　toluene,　and　55%　(at　7　L/min)　for　p-xylene.　A　UV　light　wavelength　of　254　nm　provided　greater　degradation　of　the　VOCs　than　365　nm　UV　light.　The　degradation　rates　of　p-xylene　and　acetone　in　the　gas　mixture　were　lower　than　those　of　pure　p-xylene　and　acetone.　The　opposite　trend　was　observed　for　toluene.　Acetone,　both　in　the　mixed　gas　and　pure,　had　the　highest　degradation　efficiency.　Acetone,　toluene　and　p-xylene　degradation　followed　Langmuir-Hinshelwood　kinetics.
