A study on preparation of unique TiO2/Cu2O nanocomposite with highly efficient photocatalytic reactivity under visible-light irradiation

This work deals with the unique TiO2/Cu2O nanocomposite was synthesised by a hydrothermal precipitation way and high photocatalytic degradation of target organic toxin over the photocatalytic coordination. The structure, morphology, composition, optical and photocatalytic belongings of the as-prepared nanomaterials (NMs) were analytically considered in aspect. In 80 min of exposure time, closely 94.5% decolourization proficiency and the removal rate of MB dye were attained by TiO2/Cu2O photocatalyst, which is abundantly greater than that of bare Cu2O (61.5%) and TiO2 (40%) photocatalysts (PCs) individually. The photodegradation kinetics of TiO2/Cu2O nanocomposite on MB dye was analytically discovered and the apparent rate kinetic was 5.1 folds grander related than pristine TiO2. The TiO2/Cu2O photocatalyst also maintains worthy recycling steadiness up to four successive photodegradation cycles. Moreover, these novel TiO2/Cu2O nanocomposite owns great prospective for visible-light-driven organic impurities devastation from the wastewater.
