ResumoNowadays, monitoring landfill produced gases (LFGs) is a major task for environmental safety of the areas neighboring garbage dumps.The authors have explored a novel approach to this problem.We have tested solid-state chemoresistive gas sensors to detect typical complex organic gases produced by landfill, i.e., carbon sulfide, methyl sulfide and xylene.We have prepared TiO 2 :Mo, MoO 3 :Ti, TiO + WO 3 and TiO:W mixed-oxides thin films deposited by reactive sputtering and then processed through the selective sublimation technique.The layers gave remarkable response towards carbon disulfide and xylene below the attention level for these gases.
