ZnWO nanorod-colloidal SnO quantum dots core@shell heterostructures: Efficient solar-light-driven photocatalytic degradation of tetracycline.

Zinc tungsten oxide (ZW) and colloidal SnO quantum dots (CS) were synthesized individually by hydrothermal and wet chemical methods. ZW-CS core@shell nanorods were prepared using a sonochemical method for the enhanced photocatalytic activity of tetracycline (TC) degradation. ZW-CS core@shell nanorods were systematically characterized by structural, morphological mapping and optical techniques.

Morphological guided sphere to dendrite BiVO for highly efficient organic pollutant removal and photoelectrochemical performance under solar light.

Monoclinic BiVO (m-BiVO) has been reported as promising phase for solar light driven photocatalysis. However, in the case of morphology guided BiVO with different synthetic conditions maintaining the m-BiVO phase remains a substantial challenge for achieving an efficient photocatalyst driven by solar light. Herein, a simple hydrothermal approach was used to produce well-defined template free m-BiVO dendrites with distinct branches for photo catalytically removal of organic pollutant and photocurrent generation.

Effect of annealing environment on the photoelectrochemical water oxidation and electrochemical supercapacitor performance of SnO quantum dots.

SnO quantum dots (SQD) were prepared by utilizing the soft-chemical approach. The formed SQD's were annealed in two kinds of environments: air and nitrogen (N). Each annealing environment resulted in significant improvement in the performance of water oxidation and electrochemical supercapacitor performance.

Enhanced solar-light-driven photocatalytic and photoelectrochemical properties of zinc tungsten oxide nanorods anchored on bismuth tungsten oxide nanoflakes.

At present, sustainable water supply and energy generation are the most important challenges faced by humankind globally. Thus, it is crucial to progress ecological techniques for sustainable removal of organic pollutants from wastewater and generation of hydrogen as an alternative to fossil fuels. In this study, zinc tungsten oxide (ZnWO) nanorods, bismuth tungsten oxide (BiWO) nanoflakes, and BiWO/ZnWO (BO-ZO) nanocomposites were prepared via a simple hydrothermal approach.

ZnO nanosheets-decorated BiWO nanolayers as efficient photocatalysts for the removal of toxic environmental pollutants and photoelectrochemical solar water oxidation.

Herein we report the fabrication of novel BiWO/ZnO heterostructured hybrids for organic contaminant degradation from wastewater and photoelectrochemical (PEC) water splitting upon solar illumination. The BiWO/ZnO photocatalysts were synthesized using a simple and eco-friendly hydrothermal process without the support of any surfactants. From the photocatalytic experiments, heterostructured BiWO/ZnO nanohybrid catalysts exhibited considerably better photocatalytic performance for rhodamine B (RhB) degradation under solar illumination.
