"Storage-oxidation" cycling process for indoor benzene removal at room temperature
Non-thermal air plasma assisted "storage-oxidation" cycling process was applied to indoor benzene removal at room temperature and realized over TS-1 zeolite supported AgCu catalysts. AgCu/TS-1 catalyst showed not only promising C6H6 capacity under humid condition in the storage phase, but also high oxidation efficiency of absorbed benzene with the assistance of non-thermal plasma (NTP) at a moderate discharge power of 6 W. Due to the generation of increased amounts of Cu+ and active surface oxygen species resulting from the Ag-Cu interaction, the AgCu/TS-1 catalyst showed higher benzene storage and oxidation capacity than the other catalysts. Compared with the thermal regeneration, the good humidity tolerance, non-benzene release, and low energy cost was achieved in the non-thermal air plasma regeneration, which providing a promising way for indoor benzene purification.
