“…In sample IM_ZnAl_2Ti this absorption band is shifted towards lower wavelength (3416 cm À1 ) and is followed by a broad shoulder at around 1630 cm À1 that indicate [51,52]. Peak at around 1550 cm À1 is present in samples IM_ZnAl_2Ti and IM_ZnAl_1Ti and is usually attributed to the presence of TiO 2 which is in good agreement with the XRD findings [31]. In this region a broad shoulder is detected in sample IM_ZnAl_3Ti indicating a small TiO 2 amount, confirmed by the XRD analysis [20].…”

“…In samples IM_ZnAl_3Ti and IM_ZnAl_2Ti bands in the range of 500-400 cm À1 were detected and can be assigned to the tetrahedral ZnO 4 group. This phase together with ZnO phase in samples highly contributes to photocatalytic properties and was also detected by XRD analysis [20,31]. The bands related to the presence of ZnO and Zn 2 TiO 4 phases were not detected in IM_ZnAl_1Ti sample, but a broad and wide peak was detected at $505 cm À1 that can be attributed to the Ti-O-Ti vibrations of the crystal anatase TiO 2 phase [55][56][57].…”

“…This phenomenon points towards the conclusion that in this sample the memory effect was achieved. Namely, returning of the structure of the mixed oxides into the memory of the original structure of the layered double hydroxides during the process of impregnation was present (23). For the sample B2 (10wt.% TiO 2 ), the reflections of the LDH possess higher intensity indicating a higher memory effect and return to the layered double structure in comparison with the powder B1.…”

ABSTRACT:The aim of this investigation was the synthesis of nanocomposite coatings based on Zn-Al layered double hydroxides (Zn-Al LDH) and TiO 2 . The Zn-Al LDH material, which acted as the catalyst support of the active TiO 2 component (in the content of 3 and 10 wt. %), was synthesized by a low super saturation co-precipitation method. The interaction between the Zn-Al LDH and the active TiO 2 component was accomplished by using vacuum evaporation prior to the mechanical activation and only by mechanical activation. The final suspension based on Zn-Al LDH and 10wt. % TiO 2 , impregnated only by mechanical activation, showed the optimal characteristics from the aspect of particle size distribution and XRD analysis. These properties had a positive effect on the functional properties of the coatings (photocatalytic activity and self-cleaning efficiency) after the water rinsing procedure. KEYWORDS: RESUMEN: Síntesis de un revestimiento nanocompuesto basado en TiO 2 / ZnAl hidróxidos dobles en capas.El objetivo de esta investigación fue la preparación de recubrimientos de nanocompuestos basados en Zn-Al hidróxidos dobles en capas (Zn-Al LDH) y TiO 2 . El material de LDH Zn-Al, que actuaba como catalizador del componente activo TiO 2 (en el contenido de 3 y 10 en peso.%), se sintetizó por un método de co-precipitación con baja sobresaturación. La interacción entre el Zn-Al LDH y el componente activo TiO 2 se llevó a cabo mediante el uso de la evaporación al vacío antes de la activación mecánica y sólo por activación mecánica. La suspensión final basada en Zn-Al LDH y 10wt. % TiO 2 , impregnada solamente por la activación mecánica, mostró las características óptimas desde el aspecto de la distribución de tamaño de partícula y análisis de XRD. Estas propiedades tenían un efecto positivo sobre las propiedades funcionales de los revestimientos (actividad fotocatalítica y eficiencia de auto-limpieza) después del procedimiento de aclarado de agua.ORCID ID: V.
