description	La mejora selectiva de compuestos aromáticos derivados de biomasa lignocelulósica mediante oxidación fotocatalítica se considera un proceso próspero, respetuoso con el medio ambiente y rentable. Presentamos por primera vez la aplicación de varios nano-fotocatalizadores de óxido de titanio ventajosos para la oxidación parcial selectiva sin aditivos de alcohol bencílico a benzaldehído en condiciones ambientales. Los dos materiales con mejor desempeño fueron los nanotubos de titanato.y nanonúcleos de anatasa rodeados por una fase amorfa de hidróxido de titanio. Los resultados obtenidos por las pruebas de barrido además de los cálculos de DFT nos llevaron a concluir que varias reacciones y especies activas son responsables de una manera compleja de la fotorreactividad de los materiales. Dependiendo de las características fisicoquímicas de los nanocatalizadores, así como de la irradiación de la luz (ultravioleta o azul real), se fotocatalizan diferentes mecanismos/vías de oxidación. Finalmente, mostramos que la utilización de compuestos orgánicos como la benzoquinona como eliminador oculta los riesgos debido a las interacciones con el objetivo que se convertirá en orgánico que da como resultado una descomposición fotolítica elevada incluso bajo luz azul real.

We present for the first time the application of various advantageous titanium oxide nano-photocatalysts for the additives-free selective partial oxidation of benzyl alcohol to benzaldehyde at ambient conditions. The two best-performing materials were found titanate nanotubes and nanocores of anatase surrounded by amorphous titanium hydroxide phase. The results obtained by scavenger tests on top of the DFT calculations led us to conclude that various reactions and active species are responsible by a complex way for materials’ photoreactivity. Depending on nanocatalysts’ physicochemical features as well as the light irradiation (ultraviolet vs. royal-blue), different mechanisms/oxidation-pathways are photo-catalyzed. Finally, we show that utilizing organic compounds like benzoquinone as scavenger hides risks due to the interactions with the targeted to be converted organic that results in elevated photolytic decomposition even under royal-blue light.

We present for the first time the application of various advantageous titanium oxide nano-photocatalysts for the additives-free selective partial oxidation of benzyl alcohol to benzaldehyde at ambient conditions.

Depending on nanocatalysts’ physicochemical features as well as the light irradiation (ultraviolet vs. royal-blue), different mechanisms/oxidation-pathways are photo-catalyzed. Finally, we show that utilizing organic compounds like benzoquinone as scavenger hides risks due to the interactions with the targeted to be converted organic that results in elevated photolytic decomposition even under royal-blue light.

Presentamos por primera vez la aplicación de varios nano-fotocatalizadores de óxido de titanio ventajosos para la oxidación parcial selectiva sin aditivos de alcohol bencílico a benzaldehído en condiciones ambientales. Los dos materiales con mejor desempeño fueron los nanotubos de titanato.y nanonúcleos de anatasa rodeados por una fase amorfa de hidróxido de titanio. Los resultados obtenidos por las pruebas de barrido además de los cálculos de DFT nos llevaron a concluir que varias reacciones y especies activas son responsables de una manera compleja de la fotorreactividad de los materiales. Dependiendo de las características fisicoquímicas de los nanocatalizadores, así como de la irradiación de la luz (ultravioleta o azul real), se fotocatalizan diferentes mecanismos/vías de oxidación. Finalmente, mostramos que la utilización de compuestos orgánicos como la benzoquinona como eliminador oculta los riesgos debido a las interacciones con el objetivo que se convertirá en orgánico que da como resultado una descomposición fotolítica elevada incluso bajo luz azul real.Selective upgrade of lignocellulosic biomass-derived aromatic compounds by photocatalytic oxidation is assumed as a prosperous, environmentally friendly, and cost-effective process.
