“…The amount of NH 3 chemisorption has a linear correlation to the BET specific surface area and decreases dramatically between 773 and 873 K. This decrease is probably caused by the phase transition of surface from TT-phase to Tphase. Masai et al reported the effect of alkai promoters on CuNa-ZSM-5 catalysts in the benzyl alcohol oxidation [23]. Addition of alkali neutralizes the acid sites and causes a higher yield of the partial oxidation product and a low level of deep oxidation products.…”

“…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.…”

Nano-gold particles supported on different alkaline earth oxides (viz. MgO, CaO, BaO and SrO), Gr. IIIa metal oxides (viz. Al 2 O 3, Ga 2 O 3, In 2 O 3 and Tl 2 O 3 ), transition metal oxides (viz), rare earth metal oxides ([all prepared by depositing gold on corresponding metal oxide support by deposition precipitation (DP) and/or homogeneous deposition precipitation (HDP) method] were evaluated for their catalytic performance in the liquid phase epoxidation of styrene by tert-butyl hydroperoxide (TBHP) to styrene oxide and also in the solvent-free benzyl alcohol-to-benzaldehyde oxidation (by molecular oxygen or TBHP) reactions. For the epoxidation, the catalytic performance (styrene oxide yield) of the most promising nano-gold catalysts prepared by the HDP method was in the following order: Au/MgO [

“…Catalytic vapor phase oxidation of benzyl alcohol to benzaldehyde [1][2][3][4][5][6][7][8] is a widely investigated reaction as it provides chlorine-free benzaldehyde required in perfumery and pharmaceutical industries. However, because of the formation of carbon-oxides causing very appreciable carbon loss in the vapor phase reaction, it is preferable to produce benzaldehyde more selectively by catalytic liquid phase oxidation of benzyl alcohol.…”
