description	La investigación de enfoques "verdes" y económicamente viables, como la (foto)catálisis, especialmente para la valorización de la biomasa, como la oxidación selectiva de compuestos derivados de la biomasa, como los alcoholes aromáticos, en el aldehído correspondiente, evitando las duras condiciones de reacción y la adición de reactivos, ha concentrado la atención en los últimos años. Por lo tanto, el diseño y desarrollo de nuevos fotocatalizadores para la oxidación selectiva parcial es altamente deseable. En este trabajo de investigación, se utilizaron ultrasonidos de diferentes frecuencias (22, 40, 80 kHz) y diferentes amplitudes como herramienta de síntesis para obtener nuevos materiales por el método de precipitación. Las muestras sintetizadas se caracterizaron utilizando diferentes técnicas como sorción de N2, TEM, XPS, XRD, análisis térmico y espectroscopia de reflectancia difusa. Las muestras sintetizadas utilizando una frecuencia y amplitud de ultrasonidos bajas (22 kHz) mostraron una naturaleza morfológica y estructural mixta consistente en nanoestructuras unidimensionales asimétricas (similares a nanorods), estratificadas y áreas no bien definidas, lo que condujo a elevar las áreas superficiales específicas de óxido metálico hasta 155 m2/g. Las nanoestructuras unidimensionales observadas tienen diámetros comprendidos entre 20 y 60 nm. Esta muestra reveló la mayor eficiencia de fotooxidación para la conversión selectiva de dos compuestos modelo derivados de biomasa, y más concretamente inspirados en la lignina, el alcohol bencílico y el alcohol cinamílico en benzaldehído y aldehído cinamílico, respectivamente, y por tanto el mayor rendimiento awa

Tuning the physicochemical features of titanium oxide nanomaterials by ultrasound: Elevating photocatalytic selective partial oxidation of lignin-inspired aromatic alcohols. Ultrasonics Sonochemistry, 94. https://doi.org/10.1016/j.ultsonch.2023.106306La investigación de enfoques "verdes" y económicamente viables, como la (foto)catálisis, especialmente para la valorización de la biomasa, como la oxidación selectiva de compuestos derivados de la biomasa, como los alcoholes aromáticos, en el aldehído correspondiente, evitando las duras condiciones de reacción y la adición de reactivos, ha concentrado la atención en los últimos años. Por lo tanto, el diseño y desarrollo de nuevos fotocatalizadores para la oxidación selectiva parcial es altamente deseable. En este trabajo de investigación, se utilizaron ultrasonidos de diferentes frecuencias (22, 40, 80 kHz) y diferentes amplitudes como herramienta de síntesis para obtener nuevos materiales por el método de precipitación. Las muestras sintetizadas se caracterizaron utilizando diferentes técnicas como sorción de N2, TEM, XPS, XRD, análisis térmico y espectroscopia de reflectancia difusa. Las muestras sintetizadas utilizando una frecuencia y amplitud de ultrasonidos bajas (22 kHz) mostraron una naturaleza morfológica y estructural mixta consistente en nanoestructuras unidimensionales asimétricas (similares a nanorods), estratificadas y áreas no bien definidas, lo que condujo a elevar las áreas superficiales específicas de óxido metálico hasta 155 m2/g. Las nanoestructuras unidimensionales observadas tienen diámetros comprendidos entre 20 y 60 nm. Esta muestra reveló la mayor eficiencia de fotooxidación para la conversión selectiva de dos compuestos modelo derivados de biomasa, y más concretamente inspirados en la lignina, el alcohol bencílico y el alcohol cinamílico en benzaldehído y aldehído cinamílico, respectivamente, y por tanto el mayor rendimiento awaThe research for “green” and economically feasible approaches such as (photo)catalysis especially for biomass valorization such as selective oxidation of biomass derived compounds like aromatic alcohols to corresponding aldehyde by avoiding the harsh reaction conditions and the addition of reagents concentrate the focus of attention the last years. Hence, design and development of novel photocatalyst for the partial selective oxidation is highly desirable. In this research work, ultrasonication of different frequencies (22, 40, 80 kHz) and different amplitudes was utilized as synthesis tool in order to obtain novel materials by precipitation method. The synthesized samples were characterized by using different techniques such as N2 sorption, TEM, XPS, XRD, thermal analysis, and diffuse reflectance spectroscopy. The synthesized sample by using low ultrasound frequency (22 kHz) and amplitude showed a mixed morphological and structural nature consisting of asymmetric 1-dimensional (nanorods-like), layered nano-structures and not well-defined areas, leading to elevate for metal oxide specific surface areas up to 155 m2/g. The observed 1-D nanostructures have diamentions in the range of 20–60 nm. This sample revealed the highest photo-oxidation efficiency for the selective conversion of two biomass-derived, and more specifically lignin-inspired model compounds, benzyl alcohol and cinnamyl alcohol to benzaldehyde and cinnamyl aldehyde, respectively, and hence the highest yield towards the desired aldehydes. The selective photo-oxidation activity was retained even after 5 photocatalytic cycles, while no leaching of Ti was recorded.https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000192503https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000436798https://orcid.org/0000-0003-1166-1982https://orcid.org/0000-0003-3701-6340https://orcid.org/0000-0003-3663-1122https://orcid.org/0000-0001-5996-6510https://orcid.org/0000-0001-6026-8568https://scienti.minciencias.gov.co/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000005961aqayyum@ichf.edu.pldagchem@gmail.comramon.colmenaresq@campusucc.edu.cojcarloscolmenares@ichf.edu.plhttps://scholar.google.com/citations?user=f0_QSeMAAAAJ&hl=es&oi=srahttps://scholar.google.com/citations?user=9HLAZYUAAAAJ&hl=eshttps://scholar.google.com/citations?user=9spgFMUAAAAJ&hl=es1 - 10Universidad Cooperativa de Colombia, Facultad de Ingenierías, Ingeniería Civil, Medellín y EnvigadoIngeniería CivilMedellínhttps://www.sciencedirect.com/science/article/pii/S1350417723000184?via%3DihubUltrasonics SonochemistryA.
