Efficient Room-Temperature Selective Oxidation of Benzyl Alcohol into Benzaldehyde Over Pt/BiOCl Nanocomposite

Nanoceria-modified platinum supported on hierarchical zeolites for selective alcohol oxidation

“…It has been emphasized to modify the surface properties of the support in order to not only enhance the active sites dispersion but also facilitate in activating alcohol molecules. 23,24 However, the factor that has an inuence on the catalytic performance for an oxidation is not only an easy accessibility of reactant molecules into the active sites but also the surface properties such as acid/base property of the support surface. [25][26][27] Therefore, the tunability of solid support properties would make more benet for the catalyst development.…”

Selective Catalytic Oxidation of Benzyl Alcohol by MoO2 Nanoparticles

“…The catalytic performance demonstrated by the two different catalysts was relevant and their performances in the oxidation of BzOH to BzCHO using TBHP or H2O2 with or without solvent are compared in Table 4. As shown in entries 14-16, the overall catalytic performance of the MoO2-Fe2O3 and MoO2 calcined nanomaterials was comparable or better than other catalytic nanomaterials reported in the literature [6,[23][24][25][26][27][28][29][30][31][32][33][34]. The catalysts shown in Table 4 cover a wide selection of The catalytic performance demonstrated by the two different catalysts was relevant and their performances in the oxidation of BzOH to BzCHO using TBHP or H 2 O 2 with or without solvent are compared in Table 4.…”

Site-specific deposition creates electron-rich Pd atoms for unprecedented C−H activation in aerobic alcohol oxidation

“…4c, the activation energy (Ea) of AuPd catalysts decreases from 127.0 kJ mol -1 for AuPd0.60 to 30.5 kJ mol -1 for AuPd0.006, indicating that electron-rich Pd atoms significantly reduce the activation energy of the reaction, accelerating the reaction. It is generally accepted that C-H and O-H cleavage are the key steps in alcohol oxidation [42][43][44]. To examine the reaction rate-determining step, kinetic isotope effect (KIE) was investigated using benzyl-d2 alcohol (C6H5CD2OH) and benzyl aldehyde-OD (C6H5CH2OD) as substrates over AuPd0.05 [45].…”

“…These results indicate that the cleavage of C-H instead of O-H is the rate-determining step for benzyl alcohol oxidation over AuPd catalysts. Moreover, we investigated the substituent effect with 4-methoxybenzyl alcohol and 4-nitrobenzyl alcohol as reactants [44]. As shown in Fig.…”
