Selective photocatalytic conversion of glycerol to hydroxyacetaldehyde in aqueous solution on facet tuned TiO2-based catalysts

Glycerol is selectively converted to hydroxyacetaldehyde (HAA) and H 2 in aqueous solution on TiO2-based photocatalysts. The product selectivity was verified to be strongly dependent on the facets of TiO2. Rutile with high percentage of {110} facets results in over 90% superior selectivity of HAA, while anatase with {001} or {101} facets gives only 16% and 49% selectivity for HAA, respectively.

Oxidation of some vicinal and non-vicinal diols by tetrakis(pyridine)silver dichromate: A kinetic and mechanistic study

The kinetics of oxidation of four vicinal, four non-vicinal diols and two of their monoethers by tetrakis(pyridine)-silver dichromate (TPSD) have been studied in dimethylsulphoxide (DMSO). The main product of oxidation is the corresponding hydroxycarbonyl compound. The reaction is first order in TPSD. Michaelis-Menten type of kinetics is observed with respect to the diols. The reaction is catalysed by hydrogen ions. The hydrogen ion dependence has the form : kobs = a + b (H+]. The oxidation of [1,1,2,2- 2H4] ethanediol exhibits a substantial primary kinetic isotope effect (kH/kD = 5.91 at 298 K). The reaction has been studied in nineteen different organic solvents and the solvent effect has been analysed using Taft's and Swain's multiparametric equations. The temperature dependence of the kinetic isotope effect indicates the presence of a symmetrical transition state in the rate-determining step. A suitable mechanism has been proposed.

Kinetics and mechanism of iridium(III) catalyzed oxidation of ethylene glycol by Cerium(IV) in sulfuric acid media

The kinetics and mechanism of trace iridium(III) catalyzed oxidation of ethylene glycol by cerium(IV) in sulfuric acid media has been investigated by titrimetric technique of redox in the temperature range of 298-313K. The reaction is first order with respect to Cc(IV) and Ir(III), and a positive fractional order with respect to EG. It is found that the pseudo-first order ([EG]?[Ce(IV)]?[Ir(IIl)]) rate constant, kobs, decreases with the increase of [HSO4-] and increases with the increase of [H+]. Under nitrogen atmosphere, the reaction system can initiate polymerization of acrylonitrile, indicating the generation of free radicals. On the basis of the experimental results, a reasonable mechanism has been proposed. Rate equations derived from this mechanism can explain all the experimental results. From the dependence of kobs on the concentration of HSO 4-, the kinetically active species has been found to be Ce(SO4)2. The rate constants of the rate determining step and the activation parameters have been evaluated.
