Plasma Assisted Synthe sis of Nan ostructur ed Pt/Al۲ O۳-CeO۲ Catalyst U sed for Waste Gas Stream Treatment

Emission control of VOCs is one of the priorities for environmental catalysis. Supported noble metals especially platinum on Ȗ-Al۲O۳ catalysts have been conve ntionally sy nthesized f or the oxidation of VOC s [۱]. However, the duration of these catalysts is not eno ugh for indu strial applications [۲]. In this re search, to improve th e catalyst properties a nd the catalytic performance, ceria as suitable promoter and plasma treatment with the ca talyst preparation were a pplied. Mate rials and m ethods:To this aim, the Pt (۱ wt%)/C eO۲ (۳۰ wt %)-Al۲O۳ catalyst was prepared by impregnation and modified by glow discharge plasma. Th e prepared nanocatalyst was charac terized by XRD,FESEM, BET and FTIR tec hniques, an d its catal ytic perform ance was evaluated by the catalytic oxidation of toluene in an atmos pheric U-sha pe Pyrex micro reactor.
