AgPO/NiO Composites with Enhanced Photocatalytic Activity under Visible Light.

Black NiO powders were prepared by a hydrothermal method. Moreover, the visible light-driven AgPO/NiO photocatalyst composites were successfully synthesized by in situ precipitation method. These samples were structurally characterized by X-ray diffraction and Rietveld refinement.

α-AgVO Decorated by Hydroxyapatite (Ca(PO)(OH)): Tuning Its Photoluminescence Emissions and Bactericidal Activity.

Defect-related luminescent materials have attracted interest because of their excellent optical properties and are considered as a less expensive and nontoxic alternative to commonly used lanthanide-based optical systems. These materials are fundamentally and technologically important for the next generation of full-color tunable light-emitting diodes as well as in the biomedical field. In this study, we report the preparation of α-silver vanadate (α-AgVO, AV) decorated by hydroxyapatite (Ca(PO)(OH), HA) with intense photoluminescence (PL) emissions at various HA/AV molar ratios (1:1-1:1/32) by a simple route based on chemical precipitation.
