Two 3D metal-organic frameworks (MOFs) with different structures, [Cu(4,4'-bipy)Cl]n (1) and [Co(4,4'-bipy)·(HCOO)2]n (2), were synthesized by means of a hydrothermal method using a typical ligand (4,4'-bipyridine), and characterized by elemental analyses, thermal analyses and single crystal X-ray diffraction. As MOF materials, the two complexes showed active performance for the photodegradatio...

Introduction: Advanced oxidation processes (AOPs) suggest a highly reactive, nonspecific oxidant namely hydroxyl radical (OH•), that oxidize a wide range of pollutants fast and non-selective in wastewater and water. Materials and methods: In this work, the nitrogen-doped titanium dioxide nanoparticles were primed by sol-gel method, characterized by X-ray diffraction and Scanning Elect...

The surface of ZnWO₄ nanorods was decorated with Cu₂O nanoparticles (Cu₂O/ZnWO₄) prepared through a precipitation method. The Cu₂O nanoparticles were tightly deposited on the ZnWO₄ surface and had average diameters of 20 nm. The nanoparticles not only promoted the absorption and utilization of visible light but also facilitated the separation of photogenerated charge carriers. This brought an i...

This paper reports the synthesis of a new type of Au@TiO2 yolk-shell nanostructures by integrating ion sputtering method with atomic layer deposition (ALD) technique and its applications as visible light-driven photocatalyst and surface-enhanced Raman spectroscopy (SERS) substrate. Both the size and amount of gold nanoparticles confined in TiO2 nanotubes could be facilely controlled via properl...

A new heterogeneous photocatalyst was prepared by incorporation of methylene blue into ZSM-5 zeolite. This photocatalyst effectively absorbs light in visible range of the spectrum and when irradiated with visible light, it generates reactive oxygen species (ROS) in aqueous environment. Efficiency of the photocatalyst was tested on dechlorination of a model compound 4-chlorophenol and on growth ...

We report the synthesis and application of a novel Exfoliated graphite/Selenium-Zinc oxide (EG/Se-ZnO) nanocomposite for photodegradation of methylene blue dye and its antibacterial activity. The composite was characterized using XRD, FTIR, SEM and TEM. Applicability of EG/ Se-ZnO nanocomposite as photocatalyst was investigated by the photocatalytic degradation of methylene blue as a model for ...

Microbial fuel cells convert the chemical energy conserved in organic matter wastewater directly to electrical through living microorganisms. These devices are environmentally friendly thanks their ability simultaneously produce and treatment. The output power of yeast microbial cell (YMFC) depends mainly on glucose concentration glucose/yeast ratio. Thus, paper aims boost YMFC by identifying b...
