چکیده

• Catalytic oxidation of benzyl alcohol to benzaldehyde over MnO x catalysts is analyzed in the DFT framework. Oxidation reactivity and selectivity cluster-sized Mn 4 O 8 9 catalytic models compared. Catalyst poisoning addressed by investigating formation benzoic acid following that benzaldehyde. Reaction steps related pathways are collected an original kinetic approach. Experimental strategies aimed at decreasing catalyst deactivation hence increasing proposed. The with 2 a promising option for production benzaldehyde, from both environmental economical viewpoints. In particular, highly dispersed systems feature good activity wide range temperatures, although phenomena over-oxidation and/or active sites generally recorded. On this account, density functional theory study was performed on models, namely over-oxygenated fragments, predict pattern selective aerobic alcohol. Several concur determine whole reaction process all them were compared unveil atomistic details mechanism. Moreover, assuming consecutive affects activity-stability based catalyst, also mechanism computationally addressed. A systematic comparison mechanisms fragments reveals some experimental test design alternative routes decrease undesired parasitic reactions leading deactivation. matching structural, energetic data published Data Brief journal [1].

Selective oxidation of benzyl alcohol to benzaldehyde in water by TiO2/Cu(II)/UV solar system

Selective oxidation of benzyl alcohol to benzaldehyde in aqueous solution, under acidic conditions, through the TiO2/Cu(II)/solar UV photocatalytic system, was investigated. Different commercial TiO2 samples were tested. The best result found, in terms of yield, was of 35% for benzaldehyde with respect to the initial benzyl alcohol concentration. During a single run, a partial conversion of ben...

The benzaldehyde oxidation paradox explained by the interception of peroxy radical by benzyl alcohol.

Benzaldehyde readily undergoes autoxidation to form benzoic acid on exposure to air at room temperature. Yet it can be formed in high yield from, for example, benzyl alcohol by oxidation using a variety of procedures and catalysts. Here we report the evidence to resolve this apparent paradox. It is confirmed that benzyl alcohol (and a number of other alcohols), even at low concentrations in ben...

Environmentally friendly synthesis of CeO2 nanoparticles for the catalytic oxidation of benzyl alcohol to benzaldehyde and selective detection of nitrite

Cerium oxide nanoparticles (CeO2 NPs) are favorable in nanotechnology based on some remarkable properties. In this study, the crystalline CeO2 NPs are successfully prepared by an efficient microwave combustion (MCM) and conventional route sol-gel (CRSGM) methods. The structural morphology of the as-prepared CeO2 NPs was investigated by various spectroscopic and analytical techniques. Moreover, ...

Synthesis and characterization of titanium(iv)/graphene oxide foam: a sustainable catalyst for the oxidation of benzyl alcohol to benzaldehyde

A sustainable catalyst for the selective oxidation of benzyl alcohol (BnOH) to benzaldehyde (BzH) was developed by mineralizing Ti(SO4)2 on graphene oxide foam (GOF) surface. The Ti(SO4)2/GOF was characterized by scanning electron microscopy (SEM), energy disperse spectroscopy (EDS), X-ray diffraction (XRD), solid-state NMR (SSNMR), thermal gravimetric analysis (TGA), infrared (IR) and BET anal...
