Influence of active phase composition (Mn, Ni, MnxNi10−x) on catalytic properties and performance of clinoptilolite supported nanocatalysts synthesized using ultrasound energy toward abatement of toluene from polluted air

A series of MnxNi10−x/clinoptilolite nanocatalysts with different Mn/Ni ratios were prepared by ultrasound energy and tested for total oxidation of toluene. The nanocatalysts were characterized by XRD, FESEM, FTIR, BET and EDX analysis. Characterization data showed that the catalysts prepared by the reported method exhibit highly and homogeneously dispersed nano size particle of nickel and manganese on modified zeolite. The use of bimetallic active phases optimized the physicochemical and catalytic properties compared to the single metal active phase. The Mn7%Ni3%/clinoptilolite nanocatalyst is the most active sample. This behavior is associated to the high content of manganese as active phase.201
