Catalytic activity of NaZSM-5 supported Cu catalysts with or without added alkali metal in benzyl alcohol oxidation

Oxidation of methane to methanol and formaldehyde over Co–ZSM-5 molecular sieves: Tuning the reactivity and selectivity by alkaline and acid treatments of the zeolite ZSM-5 agglomerates

“…Thus, both the UV-Vis-NIR DRS measurements and the methane activation results indicate that samples with H + as a chargecompensating cation contained more Co 2+ inside the zeolite channels. This is in good agreement with the earlier published results for Cu-ZSM-5 zeolites prepared by impregnation [52]. Indeed, Sueto et al showed that Cu-Na-ZSM-5 zeolites contain more Cu x O y species on the outer surface than Cu-H-ZSM-5, which mainly contain copper inside the zeolite channels [52].…”

Supported Nano-Gold Catalysts for Epoxidation of Styrene and Oxidation of Benzyl Alcohol to Benzaldehyde

“…Catalytic vapor phase oxidation of benzyl alcohol has been widely investigated [15][16][17][18][19][20][21][22]. However, since the carbon loss in the vapor phase benzyl alcohol oxidation is very appreciable due to the formation of carbon oxides, it is preferable to produce benzaldehyde more selectively by catalytic liquid phase oxidation of benzyl alcohol.…”

Fe(Cu)‐Containing Coordination Polymers: Syntheses, Crystal Structures, and Applications as Benzyl Alcohol Oxidation Catalysts

“…Up to now, catalytic vapor-phase oxidation of benzyl alcohol to benzaldehyde has been widely investigated. [23][24][25] The few studies on the liquid-phase oxidation of benzyl alcohol mainly focus on expensive metals, such as Ru, Pd, or Pd-Ag, [26][27] heteropolyacids [28] and some Cu, Fe, and Mn complexes. [29][30][31][32][33][34] In addition, the traditional reactions are often performed in environmentally undesirable solvents.…”
