Catalytic oxidation of polycyclic aromatic hydrocarbons (PAHs) over SBA-15 supported metal catalysts

Recent Advances in the Catalytic Oxidation of Volatile Organic Compounds: A Review Based on Pollutant Sorts and Sources

“…The observed enhancement was attributed to the increased reducibility of surface, due to the presence of V. Further increases in the V content however, was determined to have a detrimental effect on the catalytic performance, which was connected with the formation of V2O5. Mochida and co-workers 578 determined that a Pt/SBA-15 catalyst was more active than a corresponding catalyst supported on -Al2O3. Further investigation revealed that the Pt/SBA-15 catalyst was also more active than Ru/SBA-15 and Mo/SBA-15 catalysts, which was owing to differences in the chemisorption of naphthalene on these materials as weak chemisorption of naphthalene.…”

Total oxidation of naphthalene using palladium nanoparticles supported on BETA, ZSM-5, SAPO-5 and alumina powders

“…In the case of metal oxide catalysts [7] such as CeO 2 or mixed oxides (CuZnO) full conversion is reached at temperatures between 250ºC and 270ºC, respectively. Whilst for the case of metals supported on different oxides such as Pt/SiO 2 [33] the optimum temperature for naphthalene oxidation was 250ºC.…”

“…PAH compounds are mainly formed by several aromatic rings such as naphthalene (two-ring PAH), phenanthrene (three-ring PAH), pyrene or chrysene (four-ring PAH) or benzo [ghi]perylene (five-ring PAH). PAH composition differs depending on the emission source, and for example, PAHs found in diesel emissions mainly consist of two to five aromatic rings, and include naphthalene, phenanthrene, pyrene and fluoranthene [6,7].…”

Characteristics of Carbon Material Formation on SBA-15 and Ni-SBA-15 Templates by Acetylene Decomposition and Their Bioactivity Effects

“…Nickel is highly active and selective in organic reactions because of its high capability to break C-C bonds [ 33 ], which is the main reason that nickel was chosen as the catalyst in this work. SBA-15 is hydrothermally stable, and its physicochemical properties were consistent throughout the highly ordered hexagonal mesopores [ 34 , 35 , 36 ]. Thermal chemical vapor deposition (CVD) was employed in this study.…”
