“…It was observed, for example, that the product selectivity in the partial oxidation of toluene changes significantly in comparison with pristine titania. 94 The main partial oxidation product was benzaldehyde in all cases; benzyl alcohol and benzoic acid appear upon prolonged irradiation.…”

“…They reported the formation of cresols, benzaldehyde and benzyl alcohol, depending on the pH of the solution and on the used semiconductor. The formation of benzaldehyde was also confirmed by Navio et al, 16 which used acetonitrile as solvent and investigated the influence of the presence of water on the product distribution. Recently the use of a surfactant to enhance the photocatalytic reaction rate for toluene degradation has been reported.…”

O tolueno é um composto orgânico muito tóxico utilizado para a preparação de muitos outros compostos. A fotoxidação do tolueno em fase líquida foi realizada utilizando-se amostras policristalinas do TiO 2 dopado com óxidos de metais de transição, contendo diferentes fases de dióxido de titânio conhecidas como anatase, rutilo e a mistura de anatase e rutilo. O objetivo principal desse estudo foi investigar a conversão de tolueno a ácido benzóico e como cada fase modificada do TiO 2 afeta a velocidade da reação. As diferentes fases foram caracterizadas com base em difração de Raios X. Outros métodos, tais como, análises químicas, medidas de área de superfícies e cálculo do tamanho do cristal também foram utilizados para a caracterização das amostras. A fase da anatase dopada com metais de transição gerou maior rendimento do que a do rutilo dopado. A mistura de anatase e rutilo não apresentou efeito significativo. Toluene is a very noxious organic compound used for the preparation of many compounds. Liquid phase photo-oxidation of toluene was carried out using poly crystalline samples of transition metal oxide doped TiO 2 containing different phases of titania, namely anatase, rutile and mixture of anatase and rutile. The main objective was to find out the conversion of toluene to benzoic acid and how the phase modification of doped TiO 2 affects the reaction rate. The different phases of TiO 2 were determined using powder X-ray diffraction. Other methods such as chemical analysis, Surface area measurements and Crystallite size calculation were also used for the characterization of the samples. Anatase doped with transition metal oxides gives higher yield than doped rutile. Mixture of anatase and rutile has no significant effect.

“…The oxidation of 2-FA proceeds via a similar mechanism, a [4+2] cycloaddition, as DPBF, to produce the endo-peroxide, which in this case subsequently undergoes a decarboxylation reaction to yield 5hydroxyfuran-2(5H)-one as photooxidation product (Figure 3B). 39 Both photocatalysts quantitatively oxidized the 2-FA substrate, however BH2 showed to be a more efficient catalyst as full conversion was reached within 2 h instead of reaching full conversion after 5 h for BH1. TPP, like other triaryl phosphines, is slowly oxidized in air under ambient conditions.…”
